【Abstract】 According to the aim and attributes of bus body structural optimisation during conceptual design,this paper carried out the bus body structural optimisation analysis for the reduction of the body structural weight,using the simplified parameterised FE model(from conceptual model).It demonstrates,taking a bus body structure as an investigated example,that structural optimisation for conceptual design provides a method for autobody structural design enabling to improve the whole body structural performance at the early stage of development,cut down the repetition in design and shorten lead time.更多还原
