Front Car Door Modal Analysis Based on Finite Element Method

Abstract:

The car door modal analysis was an important method to obtain its dynamic characteristics. In order to analyze the natural frequency of the door, avoid resonance with the other vibration sources in the vehicle structure and reduce traffic noise, the right front door of a vehicle was made modal analysis based on the finite element method. First, the car door three-dimensional model was established in the CATIA, then it was imported into the HyperMesh to mesh, at last, imported into the Nastran, and the related settings was made to calculate the 7 modal frequencies of the door. By analysis of the vibration shape chart, the door low stiffness positions are found to provoid the reliable reference for optimizing the door design.
