摘　　要：离合器是汽车重要的传动系统,而碟簧是其主要的压紧零件,离合器的分离和接合是靠碟簧的变形实现的,所以研究碟簧的力学特性对于研究离合器的性能非常重要。文中针对碟簧在压紧过程中碟簧分离指的轴向受力问题进行模拟分析,基于ANSYS平台分析碟簧所受应力,分析分离指顶端应力集中原因,着重研究碟簧分离指顶端的约束和受力问题,便于更好地设计碟簧。The clutch is an important transmission system of automobile, and disc spring is main clamping part. The separation and connection of the clutch are realized by the disc spring deformation, so studying mechanics character of the disc spring is very necessary to the clutch. Aim at the disc spring, the paper simulates and analyses the axial stress of separated fingers of small end in the process of compressing tightly. ANSYS is used to analyze why separated fingers of small end produce stress concentration. The constraints and load of separated finger of small is emphatically studied for designing the disc spring better.
