Abstract

Abstract: The parameters of rubber model is usually obtained through a series of test of standard specimen. In the case of absent of standard specimen, it is significant in engineering application to reversely deduce the parameters of the material model with a few of information of the rubber isolator. In this paper, a new reverse deduction method based on the two material parameters in Mooney-Revlin model is proposed, with the consideration of the relationship between the two parameters C1 and C2, and hardness, and of the effect of C1 and C2 on the static characteristics of the rubber isolator. The MATLAB and ANSYS codes are applied to forecast the parameters. First of all, the value of C1+C2 is calculated under the condition of small displacement, and then the value of C2/C1 is obtained under the condition of large displacement. The material’s property of the rubber isolator is inversely designed. In order to verify the effectiveness of this method, the finite element model of a kind of rubber isolators is built, and the parameters are calculated based on the static compression characteristics. The effectiveness of the reverse deduction method is validated.

摘要： 确定橡胶隔振器材料模型的传统方法是利用标准试件，在一系列的测试之后才能得到材料模型的参数。在标准试件无法获得的情况下，反推出材料模型参数具有重要的工程应用价值。基于Mooney-Revlin模型的两个参数C1、C2与硬度之间的关系，以及C1、C2对橡胶隔振器静特性的影响，采用一种简单实用、精度较高的橡胶材料2参数Mooney-Revlin模型反推的方法。利用ANSYS和MATLAB的联合仿真计算，首先设C2 /C1 = 0，在小位移下反推出橡胶材料的硬度，然后在较大的位移范围内得到C2 / C1的值，反求出橡胶隔振器的材料属性。为验证该方法的准确性，建立某型橡胶隔振器的有限元模型，以测试得到的静压缩特性为参考依据，进行数值计算，验证该反推方法的准确性。
