以汽车用泡沫铝合金为研究对象,建立了泡沫铝合金力学性能分析模型。采用Ansys workbench软件static structure模块,利用有限元分析法对泡沫铝合金模型进行模拟分析,得出了泡沫铝合金模型总变形、等效应力以及等效弹性应变分布。结果表明,泡沫铝合金模型最大变形位于模型加压的表面,变形量为1.28×10-4mm,最大等效应力为6.73×105Pa,最小等效应力为5.54×103Pa,最大等效弹性应变为3.37×10-6。 Taking the automobile aluminum alloy foam as the research object, the mechanical properties analysis model of the aluminum alloy foam was established. Ansys workbench software static structure module was used to simulate the foam aluminum alloy model by finite element analysis. The total deformation, equivalent stress and equivalent elastic strain distribution of the foam aluminum alloy model were obtained. The results show that the maximum deformation of the foam aluminum alloy model is located on the pressurized surface of the model with the deformation of 1.28 × 10-4mm, the maximum equivalent stress of 6.73 × 105Pa, the minimum equivalent stress of 5.54 × 103Pa and the maximum equivalent elastic strain of 3.37 × 10-6.
