Lightweight Design and Stiffness Research Based on Aluminum Alloy Body of 9.6m Van
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.
