| Abstract: | The body frame of city passenger cars was studied based on the experimental modal analysis theory to analyze the vibration of the new bus body.The modal parameters such as the mode frequency,damp and shape of the frame are identified by using hammering method.The testing result can be used to improve the design of the bus body structure. |
