【Abstract】 The optimal design model of taper roller bearing with constraint is presented in this paper.The measure of adding memory function in inner loops and outer loops is taken to improve the convergence of standard SA algorithm.The simulated annealing algorithm developed is applied for optimal design of taper roller bearing.The comparison of simulation between improved simulated annealing algorithm and standard simulated algorithm show that the measure of improved simulated annealing algorithm has strong ability of overall search and the improved algorithm may give better optimization results of taper roller bearing.The optimal results can be served as reference to engineering design.更多还原
