摘　　要：运用CAE模拟软件对铝合金变速箱壳体在充型和凝固过程中的顺序和温度场进行仿真分析,观察易产生卷气、缩松等缺陷的部位,并分析原因。根据模拟分析的结果,提出相关的压铸工艺改善,即通过增加浇注系统分流道的数量以及对排溢系统进行优化设计。最后经实际生产和X光射线检测,缺陷得到改善,验证了该方案的可行性,为铸造出合格的铸件提供参考。The sequence and temperature field of aluminum alloy gearbox shell during filling and solidification were simulated and analyzed by CAE simulation software,and the defects such as gas trapping and dispersed shrinkage were observed,and the reasons were analyzed.According to the results of simulation analysis,the related improvement of die casting process was proposed,that is,by increasing the number of diverting channels in the pouring system and optimizing the design of the overflow system.Finally,through actual production and X-ray detection,the defects were improved,which verified the feasibility of the scheme and provided a reference for casting qualified castings.
