发布时间：2019-05-26 20:01
【摘要】：为了减小圆锥滚子母线与滚道的接触应力,以31313圆锥滚子轴承为对象,在考虑圆锥滚子轴承载荷随机性的基础上,以圆锥滚子母线与滚道的接触应力最大值为响应值,以凸度量为设计变量,构建滚子与滚道的接触应力最大值的Kriging模型.在此基础上,以构建的Kriging模型为目标函数,建立圆锥滚子凸度量优化模型.应用多岛遗传算法对凸度量进行寻优计算,得到优化的凸度量.结果表明:与传统的优化方法相比,优化得到的凸度量能显著降低圆锥滚子母线与滚道的最大接触应力值.
[Abstract]:In order to reduce the contact stress between tapered roller bus and raceway, 31313 tapered roller bearing is taken as the object, and on the basis of considering the randomness of tapered roller bearing load, the maximum contact stress between tapered roller bus and raceway is taken as the response value. Taking the convex metric as the design variable, the Kriging model of the maximum contact stress between the roller and the raceway is constructed. On this basis, taking the Kriging model as the objective function, the convex metric optimization model of conical roller is established. The multi-island genetic algorithm is used to optimize the convex metric, and the optimized convex metric is obtained. The results show that compared with the traditional optimization method, the convex metric can significantly reduce the maximum contact stress between conical roller bus and raceway.
