| Abstract: | This paper sets up a detailed dynamic model of the body-in-white of a bus, using mainly the shell element. According to the modal experiment results, we modified the model through adjusting the connective stiffness of the joints between parts and the mass distribution of the body, to obtain a mathematics model tallying with the actual mechanical characteristics of structure for laying a foundation for further simulation and analysis. |
