摘要

摘要: 在保证结构与实际车轮模型结构相同的条件下,建立机械弹性车轮的有限元模型,实现了车轮受力时的结构协调性和弹簧的回位功能。利用ANSYS软件对车轮进行了有限元分析,得出车轮的径向刚度。根据结构优化问题的特点,以轮辐的每段长度作为设计变量,轮胎径向刚度为优化目标,利用序列二次规划(SQP)算法,对车轮结构进行优化设计。结果表明:基于SQP算法的机械弹性车轮的结构优化,在允许范围内有效的增大了车轮的径向刚度。

Abstract: The finite element model of mechanical elastic wheel, which was similar to the practical one at most, was built. The coordination of structural deformation under pressure was ensured and the function of the restoring spring was realized. The ANSYS software was adopted to calculate the radial stiffness of the wheel. According to the characteristics of structural optimization, Using the length of each wheel rib as the design variables and radial stiffness as optimization objective, the wheel structure was optimized with the sequential quadratic programming (SQP) algorithm. The results showed that the radical stiffness of the wheel was increased effectively within the allowable range.
