摘　　要：针对新能源汽车车载充电器壳体工艺复杂,强度、气密性要求高等特点,对该壳体进行模具设计、CAE分析及缺陷预测。在Hypermesh软件中建立有限元网格,然后在ProCAST软件中对模型的流动充型、压铸模具热平衡和温度场进行分析,并对生产出的铸件进行X射线探伤观察。观察发现,CAE分析预测到的缺陷与实际探伤的缺陷相符合。Aimng at the complex process,high strength and air tightness requirements of the new energy vehicle onboard charger shell,die design,CAE analysis and defect prediction for the housing were carried out.The finite ele⁃ment mesh was established in Hypermesh,and then the flow filling of the model,heat balance and temperature field of die casting mold were analyzed by ProCAST,and X-ray flaw detection was performed on the product.The results indi⁃cate found that the defects predicted by CAE analysis can be matched with actual defects.
