| Abstract: | The basic theory of experimental modal analysis was introduced.Dynamic characteristics were studied based on the vibrations of a certain white-body mini car.Through experiments of vibration and mode experiments,different modal frequencies and modal characteristics of the car were acquired.Based on drawbacks in dynamic characteristics and working frequency of vehicles,suggestions were made for designers to improve mini-car structures. |
