摘要
本文应用子结构组合模态综合法,利用试验模态数据,在计算机上建立了一个包括汽车20Hz之前各阶弹性模态和刚体模态的整车动力学模型。为容纳尽可能多的模态数和测点数,提出了在模型计算过程中的分步计算法。
Using the method of sub-structure modal analysis and testing modal data, a dynamic model of a truck is built on computer which contains rigid-body modes and elastic modes up to 20Hz. In order to accomodate as many measuring points and modes as possible, a stepwise method is proposed.
