基于滚道线接触的串联组合型推力轴承轴圈和座圈的优化设计

Optimal Design of Shaft Washer and Housing Washer of Tandem Composite Type Thrust Bearing Based on Race Line Contact

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.
