| 1 | Protolith ages and deformation mechanism of metamorphic rocks in the Zhangbaling uplift segment of the Tan-Lu Fault Zone显示文摘Protolith ages and Indosinian deformation mechanism of metamorphic rocks in the Zhangbaling uplift segment of the Tan-Lu Fault Zone are important, unsolved problems. Our LA-ICP-MS zircon dating work indicates that protolith ages of the greenschist-facies Zhangbaling Group are 754–753 Ma, and those of the amphibolite-facies Feidong Complex are 800–745 Ma. These rocks belong to the earliest cover of the Yangtze Plate. Their ages and metamorphic features suggest that the rocks did not come from the Dabie Orogen. The Indosinian structures in the Zhangbaling Group and lower Sinian strata formed in a flatlying ductile detachment zone with a shear sense of top-to-the-SSW whereas those in the underlying Feidong Complex are characterized by ENE-WSW inclined folds developed under a ductile regime. It is suggested therefore that the sinistral Tan-Lu Fault Zone of the Indosinian period is buried under the Hefei Basin west of the Zhangbaling uplift segment and the uplift segment is a displaced block neighboring the fault zone. Detachment deformation between the upper rigid and lower ductile crust during displacement of the Zhangbaling uplift segment resulted in the formation of the flat-lying ductile detachment zone and its underlying drag fold zone of a ductile regime. The protolith ages and deformation mechanism in the Zhangbaling uplift segment further prove sinistral origination of the Tan-Lu Fault Zone during the continent-continent collision of the North China and Yangtze plates and support the indentation model for the two-plate collision that considers the Tan-Lu Fault Zone as an oblique convergence boundary. | ZHAO Tian ZHU Guang LIN ShaoZe YAN LeJia JIANG QinQin | 2014 | Science China Earth Sciences2014，57，11： | 25 |
| 2 | Neotectonic activity and formation mechanism of the Yishu Fault Zone显示文摘On the basis of comprehensive analyses of fault textures and geometry,the active methods,stress field,mechanism and time of the Yishu Fault Zone during the neotectonic period are discussed in this paper.The results show that the Yishu Fault Zone is a major mobile belt since the Quaternary.It consists of four major active faults with reverse dextral slip.Their active intensity increases eastwards and southwards.Fault-slip data from many active faults in the fault zone demonstrate that ENE-WSW compression predominated in the neotectonic period.Detailed field investigation shows that formation mechanism of shallow,active faults in the Yishu Fault Zone includes direct boundary fault reactivity,buried fault propagation,and reactivity of antithetic and truncating faults.In most cases,shallow,active faults in the fault zone are developed through direct reactivity or upward propagation of the previous four graben boundary faults. | YAN LeJia ZHU Guang LIN ShaoZe ZHAO Tian | 2014 | Science China Earth Sciences2014，57，4： | 17 |
| 3 | Features and origin time of Mesozoic strike-slip structures in the Yilan-Yitong Fault Zone显示文摘The NE-striking Yilan-Yitong Fault Zone(YYFZ) with a length of ca. 900 km is an important major fault zone in northeastern China. Its origin has been a controversial issue for a long time. Detailed field investigation and comprehensive analyses show that strike-slip faults or ductile shear belts exist as the origination structures on the both shoulders of the Cretaceous-Paleogene grabens. These strike-slip structures are dominated by brittle transcurrent faults, and appear as ductile shear belts only in the Weiyuanpu-Yehe and Shulan parts in the south and middle of the fault zone, respectively. The shear belts strike NE-SW and show steep mylonitic foliation and gentle mineral elongation lineation. Outcrop structures, microstructures and quartz c-axis fabrics demonstrate a sinistral shear sense with minor reverse component for the ductile shear belts. The microstructures suggest deformation temperatures of 400–450°C for the Weiyuanpu-Yehe shear belts and 350–400°C for the Shulan shear belt. A series of zircon U-Pb dating results for deformed and undeformed plutons or dikes in the shear belts constrain the strike-slip motion to the time between 160 and 126 Ma. It is further inferred from ages of main geological events in this region that the fault zone originated in the earliest Early Cretaceous. It is suggested therefore that the southern and middle parts of the Tan-Lu Fault Zone, which originated in Middle Triassic, propagated into northeastern China along the sinistral YYFZ under the earliest Early Cretaceous regional compression that is referred to as the Yanshan B event. The earliest Early Cretaceous initiation of the YYFZ results from both the high-speed oblique subduction of the Izanagi Plate and the final closure of the Mongol-Okhotsk Ocean, but the Izanagi Plate subduction played a major dynamic role in the fault zone origin. | GU ChengChuan ZHU Guang ZHAI MingJian LIN ShaoZe SONG LiHong LIU Bei | 2016 | Science China(Information Sciences)2016，59，12： | 10 |
| 4 | Deformation characteristics and formation mechanism of the Yunmengshan metamorphic core complex显示文摘The Yunmengshan metamorphic core complex in the middle part of the Yanshan Fold and Thrust Belt records crust extension processes of the eastern North China Craton during its peak destruction.Development of the metamorphic core complex was controlled by the generally NNE-striking Dashuiyu Shear Zone.The shear zone dips SE and becomes shallower NE-wards,leading to exposures of a ductile shear zone in the southern and middle parts and brittle faults in the northern part.Exposure structures,microstructures,and quartz C-axis fabrics indicate that the ductile shear zone belongs to an extensional shear zone with a top-to-the-SE shear sense.Deformation temperatures of 300–520°C suggest a midcrustal origin for the ductile shear zone.A ductile deformation belt in the footwall of the shear zone is only as wide as 1–3 km,indicating no widespread mid-crustal ductile flow in the region during the deformation.Zircon U–Pb dating of dykes and plutons as well as hornblende and biotite40Ar/39Ar dating demonstrate that the metamorphic core complex originated at 135 Ma and experienced intense shearing of the Dashuiyu Shear Zone,development of the supradetachment basins,and synkinematic intrusion during 135–125 Ma.The metamorphic core complex was subjected to rapid exhumation during 125–114 Ma when the Dashuiyu Shear Zone suffered continuous activity and passive doming.The shear zone and its hanging wall were cut or replaced by a series of brittle faults when they wereuplifted to a brittle regime,showing that exhumation took place in continuous extensional activities.The metamorphic core complex turned into slow exhumation in an extensional regime in the following latest Early Cretaceous.The evolution history suggests that the Yunmengshan metamorphic core complex was developed by the rolling-hinge model,a common formation mechanism for intraplate metamorphic core complexes in the North China Craton,under the continuous NW–SE extension during the Early Cretaceous(135–100 Ma). | Yin Chen Guang Zhu Dazhi Jiang Shaoze Lin | 2014 | Chinese Science Bulletin2014，59，20： | 10 |
| 5 | A comprehensive method for joint wear prediction in planar mechanical systems with clearances considering complex contact conditions显示文摘A comprehensive method to predict wear in planar mechanical systems with clearance joints is presented and discussed in this paper.This method consists of a system dynamic analysis and a joint wear prediction.As the size and shape of the clearance are dictated by wear and evolve with the dynamic response of the system,the contact between the journal and bearing could be conformal or non-conformal,which makes the contact conditions in clearance joints quite complicated.Therefore a modified contact force model is employed to evaluate the joint reaction force in this study.As the nonlinear stiffness coefficient is related to the physical and geometrical properties of contact bodies and varies with the deformation,this contact force model is applicable to different contact conditions between the journal and bearing.Furthermore,based on the Archard’s wear model,the amount of wear can be quantified in the joint.And the geometry is updated to reflect the evolving contact boundary.Then,the wear process and the contact force model are integrated into the motion equations of the system to perform coupled iterative analyses between system dynamic response and joint wear prediction.In addition,a slider-crank mechanism is simulated as an example to demonstrate efficiency of the proposed method and to carry out a parametric study on mechanical systems considering joint wear.The influence of clearance size and driving power are discussed and compared respectively.The index of concordance is introduced to quantify contributions of contact pressure and sliding distance to wear rate under different types of journal motion.This study could help to predict joint wear in mechanical systems with clearances and optimize mechanisms in design. | XIANG WuWeiKai YAN ShaoZe WU JiaNing | 2015 | Science China(Technological Sciences)2015，58，1： | 9 |
| 6 | Deformation analysis of the flexspline of harmonic drive gears considering the driving speed effect using laser sensors显示文摘Accurate description of the elastic deformation of the flexsphne is the foundation for optimization design of the structure and conjugate profiles of the harmonic drive gear.This paper proposed an experimental method to investigate the effect of the driving speed on the deformation characteristics of the flexspline.First,an experimental apparatus that integrates a special-fabricated micro-displacement platform and a pair of laser displacement sensors is developed,and the radial displacement of the flexsphne is measured in vertical and horizontal directions.Next,the deformation analyses of the flexsphne at different driving speeds are performed with our method and the conventional method,and the comparison results reveal that the radial displacement of the flexsphne is actually composed of both harmonic and random components,and the amplitude decreases and tends to zero with the increase of the driving speed,especially near the closed end of the flexsphne.Last,the mechanisms of the inherent multi-frequency and amplitude attenuation characteristics of the radial displacement of the flexsphne are discussed.It is indicated that the impact and friction existing in the flexible bearing of the wave generator is likely responsible for the existence of the random component,and the assumption of linear distribution of the flexsphne deformation along the rotating axis is invalid under high speed condition.Our research promotes the further study on the contact-impact problem of the flexible bearing of the wave generator and the transfer characteristic of the elastic deformation of the flexsphne. | MA DongHui WU JiaNing LIU Tao YAN ShaoZe | 2017 | Science China(Technological Sciences)2017，60，8： | 8 |
| 7 | Thermodynamic analysis of a space station remote manipulator with a harmonic drive that considers an integrated thermal protection layer.显示文摘To eliminate anomalies and improve the performance of a space station remote manipulator(SSRM) used in a dynamically changeable thermal environment, we analyze the thermodynamic behavior of an SSRM that considers an integrated thermal protection system(ITPS). Solar radiative heat gain and loss become equally significant as conductive heat transfers through the interior of the SSRM on orbit. A thermodynamic model of the SSRM with a sandwich ITPS structure is established on the coupling between harmonic drive and changeable thermal environment. A motion precision is proposed to evaluate thermodynamic behavior under continuously changeable thermal circumstances. Simulation results indicate that the ITPS with a corrugated sandwich structure reduces the maximum amplitude of angular position errors to 41.6%, which helps improve the motion precision of the SSRM. The feasible regions for the SSRM in the Low Earth Orbit(LEO) and Geostationary Earth Orbit(GEO) are analyzed, which shows that the proportion of feasible region in LEO is significantly larger than that in GEO. | ZHAO JieLiang YAN ShaoZe WU JiaNing MA Wei HAN ZengYao | 2015 | Science China(Technological Sciences)2015，58，11： | 7 |
| 8 | A method for detection and quantification of meshing characteristics of harmonic drive gears using computer vision显示文摘A lack of accurate description of the meshing characteristics and the corresponding frictional mechanism of the harmonic drive gear has limited progress toward modeling the hysteresis stiffness. This paper presents a method for detection and quantification of the meshing characteristics of the harmonic drive gear based on computer vision. First, an experimental set-up that integrates a high speed camera system with a lighting system is developed, and the image processing is adopted to extract and polish the tooth profiles of the meshed teeth pairs in each acquired video sequence. Next, a physical-mathematical model is established to determine the relative positions of the selected tooth pair in the process of the gear engagement, and the combined standard uncertainty is utilized to evaluate the accuracy of the calculated kinematics parameters. Last, the kinematics analysis of the gear engagement under the ultra-low speed condition is performed with our method and previous method, and the influence of the input rotational speed on the results is examined. The results validate the effectiveness of our method, and indicate that the conventional method is not available in the future friction analysis. It is also shown that the engaging-in phase is approximately a uniform motion process, the engaging-out phase is a variable motion process, and these characteristics remain unchanged with the variation of the input rotational speed. Our method affords the ability to understand the frictional mechanism on the meshed contact surfaces of the harmonic drive gear, and also allows for the dynamic monitoring of the meshing properties. | MA DongHui WU JiaNing YAN ShaoZe | 2016 | Science China(Technological Sciences)2016，59，9： | 7 |
