查询词典 chi-square test

In this paper, test research have been performed on the two important mechanical properties indicator compressive modulus of elasticity and shear modulus. Numerical simulation has been performed on the base of results of test under the situation uniform and uneven thickness of elastomer layer, which analyze internal stress distribution of the elastomeric bearing, as follows:(1) The traditional test methods of compressive modulus of elasticity test are rather cumbersome and take up experimentalists lots of time. This paper has improved the traditional test methods of compressive modulus of elasticity test, which has collected the holding-load time together to concentrate on holding load. The tests have been performed on different types of bearings, which results show that the results of the improved test method conform to the error range regulated by the standard and can effectively save time for the experimentalists, also eliminate the accumulative error.

本文主要对板式橡胶支座的抗压弹性模量、抗剪弹性模量两个重要力学性能指标进行试验研究，并在试验结果的基础上对均匀胶层厚度和不均匀胶层厚度两种情况进行数值模拟，分析橡胶支座内部应力分布规律，具体内容如下：(1)传统抗压弹性模量试验方法比较繁琐，占用试验人员大量时间，本文对传统抗压弹性模量试验方法进行了改进，将持荷时间集中起来进行集中持荷，通过对不同类型支座进行试验，试验结果表明该改进试验方法所得结果符合标准规定误差范围，为试验人员节省了大量时间，并且还消除了传统方法中的累计误差。
