在新车型的开发设计过程中,对所谓标杆车型的静动态性能测试占有非常重要的地位,所得到的静动态参数对新车型的设计很具有指导意义,能大幅度地缩短新车型的研发周期,既节约了成本又加快了新车型的上市时间。文中分别利用有限元法和试验法对市场上某款SUV轿车的白车身进行了模态分析,得到其各项模态性能参数,结果表明,有限元建模的方法是正确的,模型和分析所得的结果可用于进一步的研究工作。
In the development and design of new models, the so-called benchmarking static and dynamic performance test occupies a very important position, the resulting static and dynamic parameters of the new model is very instructive, can greatly shorten the new model development cycle , Which not only saves costs but also accelerates the time to market of new models. In this paper, the finite element method and the test method are respectively used to analyze the white body of a SUV sedan on the market, and the modal performance parameters are obtained. The results show that the method of finite element modeling is correct, and the model and analysis The results obtained can be used for further research work.
