According to the BIW of a cab as research object, the finite element model, reckons the libration shape in freedom state with this model and analysis the modal test was set up in the paper. By contrast with modal coefficient such as theinherent frequency and shape in BIW, the dynamic feature of BIW was valued and can be used as guideline of the design of body structure design. The finite element analysis model＇s availability has been examined.
