Optimization Design of a Bus Body Frame

Abstract:

This paper selects a certain type of Golden Dragon bus body structure as the research object, by using ANSYS parametric modeling, and achieve optimization process through the ISIGHT software integration ANSYS. Choose the body frame minimum total quality as optimal objective; the average stress level is introduced to the objective function when the body frame is under the bending and twisting joint working conditions. According to the bus operating conditions, restrictions including strength, stiffness, and frequency of the body frame are put forward .NSGA-II algorithm is employed to optimize the design. The results showed that: 8.08% total mass reduction of Bus Body Structure. The NSGA-II method combined with finite element method this article uses has a certain reference value on the similar structure optimization design.
