Abstract：A finite element model for Car BIW was established by HyperMesh software. Natural frequency and vibration modes of different orders were analyzed by Optistruct software. Experimental tests were also conducted to validate the simulation results. The results show that the test results agree well with the simulation results. In addition, the first torsion frequency of BIW is quite weak，which means that resonance can be brought about easily and hence optimization of the configuration is needed.
