摘　　要：通过试验与疲劳应力应变理论分析相结合的方法,研究模拟38GrMoAlA优质合金结构钢材质的巧克力裹包机正切型从动系统凸轮轴,在循环工作应力条件下的疲劳强度;提出正切型从动系统凸轮轴疲劳强度特性值的确定方法;并给出它的极限应力椭圆曲线和方程及八面体疲劳极限应力椭圆方程,供工程技术人员设计时参考和选用。Through the methods of trial for combining together with tired stress strain and theory analysis,the article studied the tangent type follower system of the chocolate bind chartered plane was stud- ied on imitating 38GrMoA1A the high-quality alloy structure steel material guildert, under the situation on circulate operate stress of fa- tigue strength, Proposed the recognize method of fatigue strength tigen - value on tangent type follower system,gave the oval curve and equation on Limiting stress together with the stress Oval equa- tion on Octahedron fatigue limit, provided for reference and choice when engineering technical personnel design.
