A Van White Body Modal Analysis

WEI Zhi-hui;HE Jun-jie;Mechanical Engineering Department,North China Institute of Aerospace Engineering;  
Finite element software Hyper Mesh and finite element modeling of a white van body were carried out,using Nastran free modal calculation,and then the results were analyzed. The first three order natural frequencies obtained,the results show that frame inherent frequency is higher than the target value,and that it won't produce resonance. This provides a theoretical basis for the vehicle structure improvement design.
