摘　　要：基于汽车电动转向器横拉杆的波纹管,论述了有限元技术在橡胶制品中的应用。通过单轴拉伸试验,采用ABAQUS进行橡胶本构方程的拟合,验证波纹管在极限工况下的强度。结果表明:试件的有限元结果与拉伸试验结果匹配良好。由此说明,用ABAQUS非线性分析技术预测橡胶制品的工况是可行的,从而缩短了试验验证的时间。Discussing the FEA application in rubber products based on the tie rod bellows of automotive steering.Through uniaxial tensile test,ABAQUS was used to fit the rubber curve to verify the strength of bellows in the limit working condition.The results show that the FEA results of the test specimen match well with the test results.Therefore,it is feasible to use ABAQUS nonlinear technique to predict the working conditions of rubber products,thus shortening the time of test verification.
