| 12 | Simplified circuit model of disk-shaped traveling wave ultrasonic motor显示文摘This paper presents a method of establishing simplified equivalent circuit model of traveling wave ultrasonic motor by using 1/2 wavelength stator with the similar vibration characteristics. Combined with the vibration mode characteristics of the composite stator, the method utilizes Hamilton principle to obtain precise solution of the simplified equivalent circuit. The model shows the mechanism of ultrasonic motor, considering the influence of non-axisymmetric vibration mode, tooth outline, anisotropy of PZT (Piezoelectric ceramic), etc. With this method, various electric parameters corresponding to different vibration modes, such as static capacitance, dynamic capacitance, dynamic inductance, dynamic resistance, equivalent input impedance, etc., can be solved. Experiments show good agreement with theoretical results. | CHU Xiangcheng LI Longtu(The State Key Laboratory of New Ceramics and Fine Processing, Dept. of Materials Science and Engineering, Tsinghua University Beijing 100084)CHEN Zaili(Faculty of Electromachine Engineering, Harbin Institute of Technology Harbin 1 | 2002 | Chinese Journal of Acoustics2002，21，3： | 1 |

| 14 | Motion modeling for teeth of traveling wave ultrasonic motors显示文摘A motion modeling for projection-teeth of travaling wave ultrasonic motors is developed, which is significant for an expansion of interface modeling between the rotor and stator. And the relationship between teeth height and displacement of a contact poiot, resonant frequency, is obtained by using the Finite Elemeat Method (FEM) corresponding to various vibration modes. It is found that teeth height, from 3 mm to 9 mm, has great impact on displacements along circumferential directions, particularly for (9,0) vibration mode, while displacement along radial direction tends to saturation for teeth height of about 6 mm. Based on the motion modeling, an ultrasonic motor with 3-D interface (3D USM) of new type is fabricated. | CHU Xiangcheng CHEN Zaili XIE Tao NIE Yinghua(School of Mechatronics, Harbin Institute of Technology Harbin 150006) | 1999 | Chinese Journal of Acoustics1999，18，4： | 1 |

| 16 | Computational analysis of vibration modes of disk-shaped piezoelectric traveling wave motors显示文摘According to Kirchhoff-Love’s assumptions, this paper establishes linear system of equations for solving eigen frequency constant and corresponding mode shape. Using engineer-ing and numerical analysis software Matlab5.2 and method of coefficient determinant searching arithmetic, eigen frequency constant and mode shape of the stator with i.d./ o.d. ratio of 0.1, 0.3, 0.35, 0.6 and different vibration modes are accurately solved and analyzed. By means of Newton interpolation method, contributions of transverse deflection amplitude and vibration energy corresponding to various modes are determined. This paper offers a valid theoretical foundation for the optimum design of the stator of disk-shaped ultrasonic motors. Furthermore, according to results of numerical analysis, several choosing principles of vibration modes are summarized. | CHU Xiangcheng LI Longtu(The State Key Laboratory of New Ceramics and Fine Processing, Dept. of Materials Science and Engineering, Tsinghua University Beijing 100084)CHEN Zaili(Faculty of Electromachine Engineering, Harbin Institute of Technology Harbin 1 | 2002 | Chinese Journal of Acoustics2002，21，3： | 0 |
