将有限元结构分析技术与数学规划方法相结合,对轴肩过渡曲线进行形状优化设计,提出用圆弧蜕变曲线作为轴肩和砂轮越程槽的过渡曲线,以降低轴肩应力集中。给出样条过渡曲线、椭圆过渡曲线、圆弧蜕变过渡曲线设计的设计实例,结果表明:圆弧蜕变曲线设计不仅有效地降低了轴肩应力集中,而且易于加工制造。
The finite element structural analysis and mathematical programming methods are combined to optimize the shape of the shoulder transition curve. The arc curve is proposed as the transition curve between shoulder and wheel overturning groove to reduce the axial stress concentration. The design examples of transition curve of spline transition curve, ellipse transition curve and circular arc transition curve are given. The results show that the design of arc transition curve not only reduces the axial stress concentration, but also is easy to manufacture.
