摘　　要：文章基于某重卡开发过程中出现的变截面板簧试验断裂问题,进行优化分析。从材料力学等应力梁的概念出发,讨论了变截面板簧的截面结构,并结合变截面板簧生产制造工艺的实际情况,讨论比例尺效应问题,提出了变截面弹簧应把最大应力点放在材料最厚位置的设计思想,通过实际优化结构进行了验证。In this paper, based on the development of a heavy truck appeared in the test of variable cross-section leaf spring fracture optimization analysis. Based on the concept of stress beam such as material mechanics, the section structure of the variable section leaf spring is discussed. The problem of scale effect is discussed in combination with the actual situation of the manufacturing technology of the variable section leaf spring. It is proposed that the maximum stress point should be placed on The design concept of the thickest material position has been verified through the actual optimization of the structure.
