乘用车狭小面积重叠追尾碰撞对商用车后下部防护装置的耐撞性要求较高。针对乘用车狭小面积追尾商用车这一碰撞形式进行耐撞性分析，通过拓扑优化得到兼顾30％、50％、100％三种追尾重叠形式的商用车后下部防护装置最佳材料分布形式，并根据拓扑优化模型进行精细设计，提出了一种新型的针对狭小面积重叠碰撞的商用车后下部防护装置。将该防护装置运用于某型商用车上，并对其狭小面积追尾碰撞的耐撞性进行了仿真验证。
乘用車狹小麵積重疊追尾踫撞對商用車後下部防護裝置的耐撞性要求較高。針對乘用車狹小麵積追尾商用車這一踫撞形式進行耐撞性分析，通過拓撲優化得到兼顧30％、50％、100％三種追尾重疊形式的商用車後下部防護裝置最佳材料分佈形式，併根據拓撲優化模型進行精細設計，提齣瞭一種新型的針對狹小麵積重疊踫撞的商用車後下部防護裝置。將該防護裝置運用于某型商用車上，併對其狹小麵積追尾踫撞的耐撞性進行瞭倣真驗證。

Higher requirements are put forward toward RUG of commercial vehicles that is car to truck underride crashes in the narrow area overlap.Aiming at this phenomenon,considering 30%, 50%,100% three kinds overlap crashes,through the topology optimization,the best material distriG bution form of RUG was obtained.According to results of topology optimization,a new kind of RUG was structured after elaborate design.Finally the new kind of RUG was applied to a certain type of commercial vehicle,and its crashworthiness of narrow area overlap crashes was validated.
