Application of Topology Optimization Design to Bus BIW Stiffness Improvement
ZHUANG Shouji
Abstract: The finite element simulation model of a bus body in white is established and its stiffness is simulated and analyzed. The floor skeleton and luggage compartment skeleton are optimized and designed with the topology optimization method. The stiffness performances of the bus body in white is effectively improved without increasing the weight.
Key words: bus body in white; stiffness improvement; topological optimization
