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   Research on image restoration of Roll-Swing imaging seeker (EI CONFERENCE) 会议论文  OAI收割 3rd IEEE International Conference on Advanced Computer Control, ICACC 2011, January 18, 2011 - January 20, 2011, Harbin, China 作者:  Zhang H.;  Zhang H. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 To achieve a correct image receiving for Roll-Swing imaging seeker  the mechanism and imaging process is analyzed. The causes of image rotation are discussed. The influence of the frame encoders' precision on imaging de-rotation quality is analyzed. The Roll-Swing imaging seeker is designed for high-speed aerocraft  thus the received images are greatly degraded due to atmospheric turbulence. A new method of image restoration is proposed for turbulence-degraded images in this paper. The method is to get point spread function (PSF) based on the estimation of optical transfer function (OTF) according to the optical system design simulation. Finally  to obtain the restored image  constrained least squares filtering is used with the known PSF. The experiment results indicate that the new restoration method has a favorable effect to satisfy requirement of the automatic target recognition. 2011 IEEE.   Motion mechanism analysis of a two-degree-of-freedom spherical motor (EI CONFERENCE) 会议论文  OAI收割 2nd International Conference on Information Engineering and Computer Science, ICIECS 2010, December 25, 2010 - December 26, 2010, Wuhan, China 作者:  Guo K. 收藏  |  浏览/下载：20/0  |  提交时间：2013/03/25 The working principle of a two-degree-of-freedom piezoelectric spherical motor using only one piezoelectric element was analyzed. The resonance frequencies of the motor's plate type piezoelectric vibrator were calculated by finite element method. The computer simulation was executed to analyze the motion trajectory of the four contact points between the stator and the sphere. Simulation results verified that the four contact points can form timing reasonable elliptical trajectories which re designed to drive the sphere to form two rotation degrees of freedom. The conclusion indicated the formation of two-dimensional movement mechanism of the spherical motor. 2010 IEEE.   Polarized Raman mapping study of the microheterogeneity in 0.67PbMg(1/3) Nb2/3O3-0.33PbTiO(3) single crystal 期刊论文  OAI收割 JOURNAL OF RAMAN SPECTROSCOPY, 2010, 卷号: 41, 期号: 12, 页码: 1735 Yang, Y; Liu, YL; Zhang, LY; Zhu, K; Ma, SY; Siu, GG; Xu, ZK; Luo, HS 收藏  |  浏览/下载：32/0  |  提交时间：2013/09/24 PHASE-TRANSITION SEQUENCE  ORTHORHOMBIC PHASE  BOUNDARY REGION  ELECTRIC-FIELD  NIOBATE  PB(MG1/3NB2/3)(1-X)TIXO3  MECHANISM  ROTATION
