摘　　要：通过SolidWork建模,接口导入,几何清理、划分网格等步骤,基于有限元软件Hyper-Work对某型军用运输车车架底板及其连接部分进行模态分析,提取相关参数和特征向量,并对各阶振型进行分析,分析结果与实际振动环境基本吻合。设计模态测试试验,对比试验结果和HyperWorks计算结果,结果基本一致。Through the model of SolidWork,port guide,geometry cleanup and automesh,frame,bottom-board and joint paints of certain type military transport vehicle are analyzed for modals based on HyperWorks. Modal parameters and modal vectors are extracted from analysis. The modal parameters are identified and vibration characteristics are analyzed. The results are consonant with tile real vibration environment. The modal experiment is designed. The test parameters are contrasted with the results calculated by HyperWorks, and they are the same.
