摘要
以某客车白车身为研究对象,采用模态试验的方法,测得在自由状态下的结构模态;同时采用Hyper Mesh软件建立车身有限元模型,通过求解得出声腔模态。综合车身结构模态、声腔模态结果对客车车身结构特性进行评价。
This paper takes the white body of a bus as the research object, uses the modal test method to measure the structural modes in the free state, and establishes the body finite element model by using Hypermesh software to obtain the interior acoustic modes by solving. Then the structure features of the bus body are evaluated through compositing the results of structure modes and acoustic modes of the body.
