Therefore  the hinge clearance and the impact of flexible components in kinetic models should be considered. In this paper  a nonlinear spring-damper hinge clearance model is considered to establish mechanical system structure of dynamic equations[46]  through a four-bar linkage hinge with multi-clearance rotation of ADAMS dynamic simulation for dynamics simulation study. Simulation results show that hinge clearance and link flexible in Four-link mechanism dynamics have a great impact on performance: connection with the clearance lead to pin holes to produce a series of collisions  and a larger initial impact force   Dynamics Modeling for Stabilized Platform of Roll-Swing Seeker Based on Lie Groups 会议论文  OAI收割 2011 作者:  Liu H.;  Chen J.;  Liu H.;  Liu H. 收藏  |  浏览/下载：8/0  |  提交时间：2013/03/28 Dynamic optimization of valveless micropump (EI CONFERENCE) 会议论文  OAI收割 2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, TRANSDUCERS'11, June 5, 2011 - June 9, 2011, Beijing, China Deng Y.

The micropump considered here is actuated by the vibration of membranes and can generate a net flow along the optimized rigid fluidic channel. The detailed layout of the micropump channel is optimized with respect to a number of factors which influence the output net flux of liquid  such as the number of actuation elements  the positions of actuation elements  the driving phase differences and the driving frequency. Accordingly  the layouts of several novel valveless micropumps are presented. 2011 IEEE.   Study on dynamic imaging on TDI CCD optical remote sensor of push-broom technology 会议论文  OAI收割 2010 作者:  Liu L.;  Liu L. 收藏  |  浏览/下载：3/0  |  提交时间：2013/03/28 Parallel estimation of translation for video stabilization (EI CONFERENCE) 会议论文  OAI收割 2010 6th International Conference on Wireless Communications, Networking and Mobile Computing, WiCOM 2010, September 23, 2010 - September 25, 2010, Chengdu, China 作者:  Wang H.;  Liu G.;  Wang H.;  Wang H.;  Wang H. 收藏  |  浏览/下载：94/0  |  提交时间：2013/03/25 Translation motion estimation is the major aspect of video motion compensation  especially in two-dimensional turntable. This paper presents a robust parallel estimation algorithm of translation in video stabilization system. The equivalent model of translation that derived is accorded with small rotation angle comparatively. A parallel algorithm based on grey mapping is used in local motion estimation to shorten the estimation time and improve the computation efficiency. After local motion vectors are calculated  a fast filter can detect the spurious vectors avoiding possible jerks. The suggested translation estimation algorithm has been implemented on NVIDIA GTX 260  the experimental results show that  the average time of the estimation and compensation finished in 16 ms/frame  and stabilize 1k1k pixels sequence gray video up to 60 frames/s. 2010 IEEE.
