Analysis of the Impact of Composite Mooney-Rivlin Constitutive Parameters on the Vertical Static Rigidity of Rubber Anti-vibration Parts for Rail Transit
Choosing appropriate constitutive parameters may contribute to improve the accuracy of the finite element simulation of small deformation of rubber.This article takes the rubber body of a certain rubber anti-vibration product for rail transit as the object of study,firstly the stress-strain curves of rubber are obtained through tensile tests on the dumbbell-shaped sample and the equal biaxial sample and then matched to get Mooney-Rivlin constitutive parameters;then the finite element simulation analysis is conducted by Abaqus,taking into account the impact of constitutive parameters matched respectively from the data of uniaxial test,equal biaxial test and uniaxial + equal biaxial test on the vertical static rigidity of the product,and compares the simulation result with the test result for verification.The analysis result shows that the parameters of rubber material has an obvious impact on the simulation result of the rubber anti-vibration product and the composite Mooney-Rivlin constitutive parameters can better predict the vertical static rigidity of the product.
