摘要
以某客车企业开发的城市客车车身骨架为研究对象,利用试验模态分析理论研究客车车身振动,采用锤击法对其进行模态测试,获得结构的模态频率、阻尼、振型等模态参数,为改进该客车的车身结构设计提供试验依据和改进思路。
The body frame of city passenger cars was studied based on the experimental modal analysis theory to analyze the vibration of the new bus body.The modal parameters such as the mode frequency,damp and shape of the frame are identified by using hammering method.The testing result can be used to improve the design of the bus body structure.
