遗传算法在橡胶超弹性材料参数反求中的应用
Applying Genetic Algorithm to Inversion of Parameters for Rubber's Hyperelastic Material
摘要
Abstract
The combination of optimization algorithm with the finite element simulation analysis can reverse the parameters of rubber materials.This method is based on the experimental data of a laminated rubber spring,and the Mooney-Rivlin hyperelastic constitutive model is selected.In the process of parameter inversion,in order to solve the problem of prematurity,poor stability and slow convergence of the traditional genetic algorithm,the coding method is changed into real number coding,and the elite retention strategy,adaptive crossover,mutation probability are also introduced into the algorithm.The stiffness characteristic curve obtained with the improved genetic algorithm is compared with the experimental results,which are in good agreement with the stiffness characteristic curve,indicating that the inversed parameters can accurately describe the mechanical properties of rubber materials.关键词
