旋转定位测试实验台的仿真及稳定性的ANSYS分析 摘 要 论文题目来自于某科研课题，要求设计测试某特定样品对γ射线吸收效果的专用试验台。测试实验要求同一样品上的任意点能进行重复测量，并且能够保证前后重复测量的重合度在实验误差范围内。基于测试实验对试验台精度与稳定性的要求，以及该设备设计改进需要，对旋转定位测试实验台进行仿真以及稳定性的ANSYS分析。 本论文运用Pro/E对旋转定位测试实验台进行了三维建模与动画仿真，利用有限元分析软件ANSYS15.0对所建立模型中的推杆、齿轮、V型槽进行静力学分析，对丝杆进行谐响应分析。Pro/E运动仿真结果表明旋转实验台的运动满足研究需求；ANSYS的静力学与谐响应分析数据表明，各零部件变形在实验误差允许范围之内。分析旋转定位测试实验台所得出的数据、总变形云图（Total Deformation）、等效应力分布云图（Equivalent Stress）、等效应变分布云图（Equivalent Elastic Strain）等为旋转定位测试实验台的后期优化设计给出了依据。 关键词：旋转定位 ANSYS Pro/E 静力学分析 有限元分析 The ANSYS stability analysis and simulation for the test bench of rotation positioning Abstract The title of this paper of comes from someone’s research project require the design of special equipment that can testing the absorb effect of specific sample for gamma ray. The test requires any point in the same sample can be repeated the measurement and ensure the repeated measurement of coincidence degree are within experimental error.Based on the test requirements of the precision stability and the improvement of design.Analysis the test bench of rotation positioning by means of the simulation of the test bench and the stability analysis of ANSYS. This paper use Pro/E establish the 3D model and animation simulation of test bench of rotation positioning ,use the finite element analysis software ANSYS15.0 chose the model push rod,gear,V groove that has been established analysis the part of static structural,pick wire rod analysis the part of harmonic response.The Pro/E motion simulation result suggest that the movement of the test bench of rotation positioning meet the research demand;The analysis data of test bench in static structural analysis and harmonic response analysis show the parts deformation in the allowable range of experimental error. The data ,total deformation equivalent stress ,equivalent elastic strain etc that get from the analysis of test bench give the basis for later stage’s optimization design.
