摘要
在分析串联组合型推力圆柱滚子轴承轴圈和座圈设计准则的基础上 ,按滚子与滚道线接触要求建立其最优化设计数学模型 ,采用机械优化设计中的约束随机方向搜索法计算轴圈和座圈的厚度、厚度变化角。
On the basis of analysis of design criterion o f shaft washer and housing washer of tandem composite type cylindrical roller th rust bearing, we present a mathematic model for optimal design in accordance wit h line contact requirement for cylindrical roller and race, design the washers t hickness and thickness variation angle by the search algorithm of constrained st ochastic direction. The obtained results show that the optimization is of good p erformance.
