摘　　要：为解决某低速载重货车驾驶室振动过大的问题,而又由于没有该驾驶室的三维模型,所以先利用便携式三坐标对该驾驶室进行了点云的采集,结合点云处理软件和三维软件建立了驾驶室三维模型,为后续的分析做准备。为了证明可以利用该模型进行后续的动静态分析和优化设计,分别利用有限元法与试验的方法对该模型进行了模态分析。通过两种方法得到的模态频率和振型基本一致,通过对比验证了有限元模型的准确,从而也证明了反求得到的驾驶室3D模型可用于后续的分析与优化。In order to solve the problem of excessive vibration of a low-speed truck cab,because there is no three-dimensional model of the cab.Firstly,achieve the point cloud by coordinate measuring machine,together with three-dimensional point cloud processing software to build a three-dimensional model of the cab subsequent analysis.In order to prove that the model can be used for subsequent dynamic and static analysis and optimization design,the model separately carried on the finite element modal analysis and experiment modal analysis.Through the modal frequencies and mode shapes of the two methods are basically the same,and by comparing verify the accuracy of the finite element model;Thus it is also proved that the use of reverse to get 3D model can be used for subsequent analysis.
