With one carbody of CRH5 EMU as a carrier, this paper uses Hyper Mesh and 1-DEAS software to carry out the modal calculation of carbody with and with out the hanging equipment. It uses three methods to simulate equipment, when it is hung,then analyzes the impact on the result of each method. It plays a significant role in modal analysis of carbody in the preparation.%以CRH5某车体为载体,应用有限元软件HyperMesh和Ⅰ-DEAS对未吊挂和吊挂设备的车体分别进行了模态计算,吊挂设备时用了3种方案模拟设备.分析了各方案对结果的影响.对精确的计算车体整备状态下的模态有很重要的意义.
