| Abstract: | Abstract： Fuel efficiency and safety is the focus of bus and coach body research. This paper aims to reduce the bus body weight with satisfying strength and stiffness of fuU-monocoque bus body and normal deformation distribution of car body structures. Static stiffness analysis of bus body structure was carried out by FE method, and the bus body structure and the component section shape modified according to the simulation results of the deformation and stress distribution of bus body in static load. Results of the static load test shows that the improved lightweight bus body structure met the body frame stiffness and strength requirements and the lightweight body frame method is therefore feasible. |
