Abstract：To developa van-type cargo body that is both balances economy and safety，aluminum alloy is used to replaceseelandaprefabricated structureis designed.Byestablishinggeometricandfiniteelement models，strength analysesundervertical impact，steering，torsion，braking，and other working conditionsareconducted basedonactual operatingconditions.Rigidityanalysesof thefrontwall，sidewals，andrearwallarealsoperformed，as well as analysesoftrampling，loadingandunloading，andsnow load.Theresultsshow thatalthoughthestrength analysis is satisfactory，thetorsionisclosetothematerialyieldstrengthandneedstobeappropriatelystrengthened.Therigidity analysis indicatesthat，exceptforthefrontwall，theresidualdeformationofotherpartsissmall，alowingforweight reduction and optimization.In trampling，loading and unloading，and snow load analyses，the cargo bodyperforms well.
