摘要

摘要: 以圆柱对平面接触特性研究为基础,提出了榫头接触面由直平面和部分圆弧面组成的结构方案,与典型的圆柱接触面榫结构方案对比,给出了设计结果.进而基于微动疲劳考虑,分别选择了最大综合参数FFD(fretting fatigue damage)最小和最大接触应力最小作为优化目标,对两种榫接触面设计方案分别进行了优化分析,结果表明以最大综合参数FFD最小为优化目标效果更好.

Abstract: In the foundation of the contact characteristic research for an arc surface to a plane, the structure scheme of the tenon contact surface which is composed of the straight plane and the partial circular arc surface was proposed in this paper. The design results of the scheme were given and compared with that of the contact surface with the typical cylindrical structure. And then, in consideration of the fretting fatigue,the two structure design schemes of tenon contact surface were optimized and analyzed in the selection of minimizing the maximum synthesizing parameter FFD (fretting fatigue damage) and the maximum contact stress respectively as the optimization objective. The results show that minimizing the maximum synthesizing parameter FFD as the optimization objective is better.
