| Abstract: | As to the dynamic characteristics of a truck box body with electric wheels, a method is proposed to improve the box body structure based on modal analysis results. The finite element model of the box body structure is built using Patran, the mode is analyzed by MSC Nastran, and the dynamic parameters of the box body structure are obtained. According to the modal analysis results, the box body structure is improved and its natural frequency and vibration shape are improved well. The research results can lay a basis for the optimization design and fatigue life prediction of dumping truck box body with electric wheels. |
