The finite element method was used to analyze the anti-deformation performance of the cargo compartment of the van.Under the internal impact condition,the wall panel and the compartment door are impacted by the internal load,and the residual deformation after unloading is 0.01~0.5 mm,which meets the requirement of no more than 12 mm in the standard.Under the snow load condition,when loading to 400 mm,there is no residual deformation after unloading,and when loading to 600 mm,the residual deformation after unloading is 1.7 mm,indicating that the roof has a strong anti-deformation ability.There is room for further weight reduction in the cargo compartment of the van,and it can provide a reference for the design of other types of cargo compartments of the van.
