【摘要】 交通领域作为最大排放源之一，汽车轻量化成为实现双碳目标的有效途径。将9.6m中型厢式货车厢体设计变更为铝合金材料，建立该车厢的三维模型及有限元模型，针对厢体不同构件特点划分不同网格，并在国家及行业标准的测试工况下进行结构分析，确保厢体所受应力及残余变形满足标准。仿真结果表明：该车厢既满足原有安全可靠的要求，也具有更小体积质量、更耐腐蚀、更大冲压塑性等特点。更多还原

【Abstract】 As one of the largest sources of emissions in the transportation sector, vehicle lightweight has become an effective way to achieve the goal of dual carbon. A 9.6-meter medium-sized van body is substituted with aluminum alloy material, a three-dimensional model and a finite element model of the carriage are established. According to the characteristics of different components of the cabin, different grids are divided, and their structures analyzed under the test conditions of national and industry standards to ensure that the stress and residual deformation of the cabin meet the standards. The simulation results show that the carriage not only meets the original requirements of safety and reliability, but also has the characteristics of smaller specific gravity, more corrosion resistance and greater stamping plasticity.更多还原
