摘　　要：结合近期某防护型越野汽车的研制工作,提出了一种桁架承载式复合材料薄刚壳多级防护的汽车轻装甲结构.该结构介于传统无车架重装甲承载式车身与传统有车架越野汽车的非承载式车身之间,是一种轻装甲承载式结构的新型车身.根据CAD的车体结构、底盘件及安装支架设计,并依据CAE的车体结构有限元仿真与优化分析,提出了该车身桁架布置的优化方案.根据车辆不同工况要求,对车身施加了相应的边界条件和载荷,进行了车身结构强度分析,并通过车辆的测试和试验,证明了该车身结构的合理性和先进性.Body structure and stiffness of light off-road vehicle strongly influence the vehicle driving performance. According to the protective type off-road vehicle research work recently, a kind of with truss by composite thin steel shell and multiple protective light armor structures was put forward. This structure is different from traditional armored load bearing body without frame, or traditional off-load bearing body with frame, which is in-between the tWO traditional bodies and a new body with a light armor and load bearing structure. According to the CAD modeling for body structure, chassis parts and mounting bracket design, the CAE of body structure with finite element simulation and opti- mization analysis, the optimization schemes of the body truss layout was proposed. Under different driving conditions of the vehicle, the corresponding boundary conditions and the load are exerted on the body, and the body structure strength is analyzed. By the measuring and testing of vehicle, the body structure＇s rationality and advancement was proved.
