Wave generator is combined with an elliptic cam and a flexible bearing around it. Flexspline is a structure of single wave with the same teeth. The output shaft is supported by a single cross-roller bearing. Ball screws connected the output shaft translate the rotational motion to the linear motion  and drive the focusing mirror repeated moving along the linear guide. The output rigid wheel is connected with absolute encoder to detect displacement of focusing movement. It has the characteristics of big transmission ratio  high precision  compact structure  high efficiency and smooth running etc. According to the practical application of this harmonic gear drive in the space camera  the location relationship between the displacement of focusing structure and the focal plane movement is derived  and the system error is analyzed  its accuracy is tested with the open-loop control method. Experimental results show that transmission ratio of the instrument is 1:70  repeated positional accuracy is 2m  which meet the requirements for use. 2010 SPIE.   Three dimensional study of harmonic operation at the Shanghai deep ultraviolet free electron laser 期刊论文  OAI收割 CHINESE PHYSICS C, 2010, 卷号: 34, 期号: 1, 页码: 6 Deng, HX(邓海啸）; Bei, H（卑华）; Dai, ZM（戴志敏） 收藏  |  浏览/下载：20/0  |  提交时间：2012/04/11 harmonic operation  linear harmonic  superradiant   Dynamic evaluation system for interpolation errors in the encoder of high precision (EI CONFERENCE) 会议论文  OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China 作者:  Liang L.-H.;  Sun Y.;  Sun Y.;  Wan Q.-H. 收藏  |  浏览/下载：33/0  |  提交时间：2013/03/25 In order to measure dynamic interpolation errors of photoelectric encoder of high precision  the dynamic evaluation system of interpolation errors is introduced. Firstly  the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then  the analysis of harmonic wave with the FFT is processed. Compared with the standard signal  the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple  fast  high precision  and can be used in the working field of the encoder. 2009 SPIE.   Energy identities for Dirac-harmonic maps 期刊论文  OAI收割 CALCULUS OF VARIATIONS AND PARTIAL DIFFERENTIAL EQUATIONS, 2007, 卷号: 28, 期号: 1, 页码: 121-138 作者:  Zhao, Liang   |  收藏  |  浏览/下载：20/0  |  提交时间：2018/07/30 Dirac-harmonic map  non-linear sigma model  energy identity   Unicyclic graphs with exactly two main eigenvalues 期刊论文  OAI收割 APPLIED MATHEMATICS LETTERS, 2006, 卷号: 19, 期号: 11, 页码: 1143-1147 作者:  Hou, Yaoping;  Tian, Feng   |  收藏  |  浏览/下载：16/0  |  提交时间：2018/07/30 spectra of a graph  main eigenvalues  unicyclic graphs  harmonic graphs  2-walk linear graphs   Dirac-harmonic maps 期刊论文  OAI收割 MATHEMATISCHE ZEITSCHRIFT, 2006, 卷号: 254, 期号: 2, 页码: 409-432 作者:  Chen, Qun;  Jost, Juergen;  Li, Jiayu;  Wang, Guofang   |  收藏  |  浏览/下载：11/0  |  提交时间：2018/07/30 Dirac-harmonic map  non-linear sigma model  removable singularityt   Gaussian Beams of Gravitational Wave 期刊论文  OAI收割 理论物理通讯(英文版), 2005, 期号: 8, 页码: 851-854 作者:  Huang CG(黄超光) 收藏  |  浏览/下载：16/0  |  提交时间：2015/12/10 The standard and high-order Gaussian beam solutions for gravitational wave is obtained in the linear approximation of vacuum Einstein equation under harmonic conditions.   A simplified formulation of linear and nonlinear spectroscopy of ordered molecular systems 期刊论文  OAI收割 CHINESE JOURNAL OF CHEMICAL PHYSICS, 2004, 卷号: 17, 期号: 3, 页码: 362-368 作者:  Wang, HF   |  收藏  |  浏览/下载：11/0  |  提交时间：2019/04/09 Linear And nonLinear Spectroscopy  Second Harmonic Generation  Sum Frequency Generation Vibrational  Spectroscopy  General Orientational Functional  Ordered Molecular System
