| Abstract: | With the prototype of an MPV, this paper addresses the research on the stiffness cutting of bonnet, including inner and outer panel, with the combinative method of light material replacement and structure optimization. Meanwhile the problem of hinge rupture during the crash test is solved. The bonnet with lightweight design satisfies the requirements of static stiffness and crashworthiness performante of full vehicle. The lightweight method is verifi reduction effect of inner panel and outer panel of the ed and satisfactory weight reduction is obtained. The bonnet are 46. 38% and 50.18% respectively. |
