摘要：
As a reference to some minibus,establishing the Vehicle FEM Model including Body and Frame,and discussing the effect of joint simulation on vehicle modal analysis resultusing the method based on environment incentive operational modal parameter identification to obtain vehicle modal,and compare test result with simulation result, it proves that the method of weld joint simulation is more accurate;At last, the FEM Model of Interior cavity is established and the NVH problems of the minibus are found and the improvements are Put forward.
