چکیده

With due attention to the fact that the local and foreign vehicle industries are changing and modifying the previous designs in order to produce new designs, the components of self-propelled are to be differently analyzed. Static and dynamic analysis is one of them. In this paper, chassis and body of a o-457 bus were studied and analyzed under finite element method (using ANSYS).This process was begun with three dimensional modeling of suspension system, chassis and structure of bus. At first, as an initial stage, a static analysis was performed on the bus to assure the resistance of its chassis. In the next stage, the dynamic analyzed including modal and transient analyses were carried out. In the transient analysis, the symmetric and asymmetric simulations were done in order to test structural resistance and flexibility of the bus.
