| 1 | Study on motion of rigid rod on a circular surface using MHPM显示文摘In this paper motion of rigid rod on a circular surface is studied analytically.A new analytical method called modified homotopy perturbation method(MHPM)is applied for solving this problem in different initial conditions to show capability of this method.The goveming equation for motion of a nigid rod on the circular surface without slipping have been solved using MHPM.The efficacy of MHPM for handling nonlinear oscillation systems with various small and large oscillation amplitudes are presented in comparison with numerical benchmarks.Outcomes reveal that MHPM has an excellent agreement with numerical solution.The results show that by decreasing the oscillation amplitude,the velocity of rigid rod decreases and for A=w3 the velocity profile is maximum. | Seiyed E.Ghasemi Ali Zolfagharian D.D.Ganji | 2014 | Propulsion and Power Research2014，3，3： | 7 |
| 2 | Topology-Optimized 4D Printing of a Soft Actuator显示文摘Soft robots and actuators are emerging devices providing more capabilities in the field of robotics.More flexibility and compliance attributing to soft functional materials used in the fabrication of these devices make them ideal for delivering delicate tasks in fragile environments,such as food and biomedical sectors.Yet,the intuitive nonlinearity of soft functional materials and their anisotropic actuation in compliant mechanisms constitute an existent challenge in improving their performance.Topology optimization(TO)along with four-dimensional(4D)printing is a powerful digital tool that can be used to obtain optimal internal architectures for the efficient performance of porous soft actuators.This paper employs TO analysis for achieving high bending deflection of a 3D printed polyelectrolyte actuator,which shows bending deformations in response to electrical stimuli in an electrolyte solution.The performance of the actuator is studied in terms of maximum bending and actuation rate compared with a solid,uniformly 3D printed and topology-optimized actuator.The experimental results proved the effectiveness of TO on achieving higher bending deformation and actuation rate against a uniformly 3D printed actuator. | Ali Zolfagharian Martin Denk Mahdi Bodaghi Abbas Z.Kouzani Akif Kaynak | 2020 | Acta Mechanica Solida Sinica2020，33，3： | 3 |

| 4 | Analysis of nano droplet dynamics with various sphericities using efficient computational techniques显示文摘Motion of a vertically falling nano droplet in incompressible Newtonian media with initial velocity is investigated. The instantaneous velocity and acceleration are carried out by using the variational iteration method(VIM) and homotopy perturbation method(HPM), which are analytical solution techniques. The obtained results are compared with Runge–Kutta method in order to verify the accuracy of the proposed methods. The results show that, the analytical solutions are in good agreement with each other and with the numerical solution. Also, the effects of sphericity(?) on the velocity and acceleration profiles of the nano droplet are explained. Moreover, the results demonstrate that the VIM-Padé and HPM-Padé are very effective in generating analytical solutions for even highly nonlinear problems. | Ali Zolfagharian Milad Darzi S.E.Ghasemi | 2017 | Journal of Central South University2017，24，10： | 1 |

| 13 | Numerical study on polymer nanofibers with electrically charged jet of viscoelastic fluid in electrospinning process显示文摘Electrospinning is a useful and efficient technique to produce polymeric nanofibers. Nanofibers of polymers are electrospun by creating an electrically charged jet of polymer solution. Numerical study on non-Newtonian and viscoelastic jets of polymer nanofibers in electrospinning process is presented in this work. In particular, the effect of non-Newtonian rheology on the jet profile during the electrospinning process is examined. The governing equations of the problem are solved numerically using the Keller-Box method. The effects of yield stress and power-law index on the elongation, velocity, stress and total force are presented and discussed in detail. The results show that by increasing the values of yield stress, the fluid elongation is reduced significantly. | P.Valipour H.Zaersabet M.Hatami Ali Zolfagharian S.E.Ghasemi | 2017 | Journal of Central South University2017，24，10： | 0 |
| 14 | 4D printing of soft orthoses for tremor suppression显示文摘Tremor is an involuntary and oscillatory movement disorder that makes daily activities difficult for affected patients. Hand tremor-suppression orthoses are noninvasive, wearable devices designed to mitigate tremors. Various studies have shown that these devices are effective, economical, and safe;however, they have drawbacks such as large weight, awkward shape, and rigid parts. This study investigates different types of tremor-suppression orthoses and discusses their efficiency, mechanism,benefits, and disadvantages. First, various orthoses(with passive, semi-active, and active mechanisms) are described in detail.Next, we look at how additive manufacturing(AM) has progressed recently in making sensors and actuators for application in tremor orthoses. Then, the materials used in AM are further analyzed. It is found that traditional manufacturing problems can be solved with the help of AM techniques, like making orthoses that are affordable, lighter, and more customizable. Another concept being discussed is using smart materials and AM methods, such as four-dimensional(4D) printing, to make orthoses that are more comfortable and efficient. | Moslem Mohammadi Ali Zolfagharian Mahdi Bodaghi Yong Xiang Abbas Z.Kouzani | 2022 | Bio-Design and Manufacturing2022，5，4： | 0 |
