| 摘 要： | 轴承的生热率与轴承的使用寿命密切相关,为了减小轴承的生热率,以滚动轴承拟静力学分析和滚道控制理论为基础,求得轴承运转过程中的相关参数,进而得到轴承生热率.将轴承最小生热率为目标函数,通过Kriging模型和粒子群优化算法相结合的方式进行了轴承结构参数优化.对NSK 7016A5轴承的研究结果表明:轴承结构参数优化后,轴承整体和轴承内外圈生热率均变小.Kriging模型和粒子群优化算法相结合的轴承结构参数优化方法取得了良好的设计效果,并且提高了轴承的设计效率.

| Abstract: | There is a close relationship between heat generation rate and the life of the bearing. To decrease the heat generation rate of the bearing, associated parameters of the working bearing were obtained based on pseudo statics analysis and raceway control theory of the bearing, and then, the heat generation rate of the bearing was further acquired. The Kriging model and particle swarm optimization algorithm were proposed for optimizing structure parameters of the bearing to obtain the minimum heat generation rate of the bearing. Taking the NSK-7016A5 bearings as an example, the results show that the total heat generation rate of the bearing and inner and outer rings can be decreased after optimization of bearing structure parameters. The combination method of Kriging model and particle swarm optimization for optimizing bearing structure parameters could obtain satisfactory design results, and increase bearing design efficiency as well. |
