摘要:对某微型商用车车架、货箱、驾驶室的模态分析发现,货箱的一阶模态频率仅为车架的
三分之一左右,为了解决这一工程问题,论文利用 HyperWorks/OptiStruct 对货箱进行了拓扑结构
优化,并进行了重新设计。优化后的货箱一阶模态频率与车架、驾驶室接近,从而解决了货箱、车
架及驾驶室固有频率的匹配问题,提高了车辆的使用寿命和舒适性。论文的研究成果对车辆设计和
改进有重要的意义。

Abstract: The result of normal modal analysis of a mercial vehicle shows that the first modal
frequency of cargo body is far lower than that of frame and driver room. To avoid the disadvantage,
Structural topology optimization of the cargo body is carried out in HyperWorks software environment,
and the structure of cargo body is redesigned based on the optimization result. The first modal
frequency of the new cargo body is similar to that of frame and driver room. The research method
mentioned in this article has important significance in design and amelioration of vehicle.

1 引言
某微型商用车的货箱与车架通过六个螺栓连接,承受着货物和从车架传来的地面激励的双重作用,是
主要的承载部件之一。如果货箱和车架、驾驶室固有频率不匹配,则容易导致车辆局部变形过大,出
