Optimization Design of the Middle Frame of a 10.5 m Bus
LI Teng,YAN Dong,ZHU Hongjun
Abstract: The authors carry out the optimization scheme design,the CAE comparative analysis of stiffnessand strength,and the comparison of scheme cost for the middle section frame of a 10.5 m bus.The resultsshow that the mechanical properties of the optimized middle section frame are improved,and the cost is re-duced somewhat.
Key words: bus frame; middle frame; structure optimization design
