【摘要】 板式橡胶支座力学性能E的测试是评价其力学性能是否符合设计要求，是否符合质量要求的必要步骤。 原有的此类型测试装置基本上是在其它类型试验机基础上经一定技术改造而来的，到目前为止市场上尚未有专用的具有自动控制功能的板式橡胶支座力学性能E的测试装置。因此研究此类型的测试装置具有十分重要的现实意义。 本文先对测试装置的各组成部分即装置的主机结构、测量子系统以及软件子系统进行了介绍。然后利用ANSYS分析软件，重点对系统中主机结构的上、下压板的应力应变进行分析研究，找出在不同的边界条件下，上、下压板的应力应变变化规律，为设计出合理的上、下压板厚度提供理论依据并确定了纵向位移传感器在上、下压板的最佳安装位置。 弯扭组合主应力测定实验在材料力学实验中占有重要的地位，作者指出了老式弯扭组合实验设备的缺点，通过对所测点A(B)处应力应变状态分析，确立了设计超小型化弯扭组合实验装置的理论基础、设计原则，设计出了体积小，加载简单，结构尺寸合理，精度高的超小型化弯扭组合实验装置。更多还原

【Abstract】 Testing elastic modulus E of plain elastomeric bearings is the essential step on deciding whether their mechanical properties conform to demand of design and quality.The original types of test devices are obtained through technically reforming traditional types of test machines. Up to day mere are no available test devices for elastic modulus E of plain elastomeric bearings, which possess automatic control function. Therefore it is real value to research this problem.This article first introduces some things about the device. Then using ANSYS analysis software , we are with an emphasis on studying stress and strain of up-press-board and low-press-board of main engine structure and find the rules for the stress and strain of up-press-board and low-press-board in the different boundary conditions. These rules provide theory for designing reasonable thickness of up-press-board and low-press-board. This article also discusses the best locations for installing vertical displacement sensors.It is importance of the experiment about measuring principal stress combined bending with torsion in mechanics of materials. This paper points out shortcomings in the traditional experimental devices combined bending with torsion and establishestheory and principles for designing superminiaturizational experimental device combined bending with torsion through analyses of stress and strain state at the measured point A(B) . It also designs the superminiaturizational experimental device ,which has smaller space and more precision and has more reasonable structure measurements in this paper.更多还原
