摘要
试验模态分析是了解结构动特性的重要工具。介绍了客车车身的试验模态分析结果，并与国外同类型车身模态试验结果进行了对比分析。通过对比分析，对某客车车身提出了相应的改进措施，并评价了改进后车身的动态性能，使该型客车车身在短时间内定型。
Test modal analysis is an important means for understanding dynamic characteristics of construction. The paper presents the results of test modal analysis of a bus body,cornparing with those of the similar type of foreign motor vehicle bodies. Then corresponding improvement measures are suggested for the body and dynamic characteristic of modified body is evaluated,which makes the design of the bus body to be appraised in a short time.
