摘　　要：圆锥滚子轴承在农业机械中具有非常广泛的应用,而传统的圆锥滚子轴承设计方法存在明显的不足。在分析利用经典模拟退火算法(CSAA)实现圆锥滚子轴承优化设计存在的缺点之后,以分阶段、分领域函数以及最优解保留为搜索策略,提出了改进模拟退火算法(ISAA)优化设计模型,克服传统方法中存在的全局寻优能力弱及对初值敏感的缺点。Tapered roller bearings have been widely used in agricultural machinery, while the traditional design methods have obvious deficiencies. After analyzing the shortcomings of classical simulated annealing algorithm （CSAA）, the optimization design model of improved simulated annealing algorithm （ISAA） is put forward by taking phasing, sub-domain function and optimal solution reservation as the search strategy. The optimization can overcome the shortcomings of traditional methods, like weak ability of global searching and sensitivity to initial values.
