A formula to calculate fundamental frequency is proposed using Rayleigh-Ritz method  and a method of is analyzed. By means of OPTISTRUCT software  the maximum fundamental frequency is converted to object function  the deformation under the gravity and the mass are assigned to state variable  wall thicknesses of the structure are converted to design variables. The analysis and test results indicate that the fundamental frequency of designed optical supporting structure has been improved 37.2 Hz from 96.9 Hz  which guarantee the reliability of the sweep mechanism  and the rotate error is 4.89  which is satisfied for the rotate accuracy in plunge angle. The method of optimization has a certain instructional significance for the design of supporting structures in aviation remote sensor. 2011 IEEE.   ON RITZ METHOD OF AN INTEGRO-DIFFERENTIAL EQUAITON 期刊论文  OAI收割 ACTA MATHEMATICA SCIENTIA, 2009, 卷号: 29, 期号: 3, 页码: 687-696 作者:  Ding Xiaqi;  Luo Peizhu   |  收藏  |  浏览/下载：13/0  |  提交时间：2018/07/30 Zeta-function  Ritz method  explicit formula   Global superconvergence in combinations of Ritz-Galerkin-FEM for singularity problems 期刊论文  OAI收割 JOURNAL OF COMPUTATIONAL AND APPLIED MATHEMATICS, 1999, 卷号: 106, 期号: 2, 页码: 325-344 作者:  Li, ZC;  Lin, Q;  Yan, NN   |  收藏  |  浏览/下载：15/0  |  提交时间：2018/07/30 elliptic equation  singularity problem  superconvergence  combined method  coupling technique  finite-element method  the Ritz-Galerkin method  penalty method  hybrid method   Numerical Methods for Inverse Problem of HeatConduction with Unknown Boundary Based on Variational Principles with VariableDomaln 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1992, 卷号: 1, 期号: 4, 页码: 241,248 Liu Gao-Lian1; Zhang Dao-Fang*2 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/13 variable-domain variational method  inverse heat conduction problem  unknown boundary  generalized Ritz method  flnite element method
