摘要
把整车系统划分为簧上和簧下两大部分,将模态综合技术应用于车身结构动力特性的分析。推导出了车身的动力学方程及车身构件动应力的数字模拟计算公式。自编了计算车身结构动应力响应的计算机程序CSGJ—3。
In this paper, there are two parts in the automobile structure:upon springs and down springs.The comprehensive modal technology is applied tothe dynomic analysis of a bus body to get the dynamic equations of the structu-re and the mathematical approximate formwlars of computing the dynamic stressof the bus body.And the relevant computer programme CSGJ-3 is worked outby ourselves.
