为实现某空投运载车副车架的轻量化设计，利用ABAQUS 软件对空投运载车在极限工况下的着陆冲击过程进行建模仿真，进而对副车架的刚强度进行了分析，并提出了相应的改进措施。运用尺寸优化的方法对副车架进行详细设计，确定了副车架主要矩形管和加强筋的厚度。
위실현모공투운재차부차가적경양화설계，이용ABAQUS 연건대공투운재차재겁한공황하적착륙충격과정진행건모방진，진이대부차가적강강도진행료분석，병제출료상응적개진조시。운용척촌우화적방법대부차가진행상세설계，학정료부차가주요구형관화가강근적후도。
To realized the lightweight of the airdropping truck’s sub frame,the model of truck for landing impact was built by using the ABAQUS in the worst conditions,then the stiff-ness and strength of sub frame was been ana-lyzed.Based on the analysis results,the improved measures were put forward.The detailed design of sub frame was accomplished by using size optimi-zation,and the thicknesses of maj or rectangular pipes and brackets were determined.
