摘要
以客车车身结构为研究对象,介绍了模态的理论基础,通过对模型进行模态计算,获得了该车车身骨架的频率特征和振型,最后对模态计算结果进行了分析。实例计算表明,模态分析对改善车身结构强度具有指导意义,为后一步的动态响应计算、分析打下了基础。
This paper described the theory of modal base on bus structure. The frequency characteristics and mode shapes is acquired through the modal computation. Finally, the result of modal is analyzed. The example indicated that modal analysis has instructive meaning in improving the strength of bus. It lays the foundation on post-step calculation of dynamic response.
