| 摘 要： | 针对某商用车前下部防护装置刚度不足的问题,应用拓扑优化与参数优化方法,对原车前下部防护板式支架结构进行重新设计,并在支架前端加装碰撞缓冲盒形梁.应用LS-DYNA软件对新设计的防护装置进行了仿真分析.结果表明,新的前下部防护装置不仅解决了原车防护装置刚度不足的问题,即具有碰撞阻挡功能,且能起到缓冲吸能的作用.

| Abstract: | In view of the problem of insufficient stiffness of the front underrun protective device(FUPD) in a commercial vehicle,the plate-type bracket structure of original FUPD is redesigned by applying both topology and parameter optimization techniques with a crash buffering box beam added on.A simulation analysis is performed on the redesigned FUPD with LS-DYNA.The results show that the new FUPD not only solves the problem of inadequate stiffness,i.e.gains the function of front underrun resistance,but can also p... |
