摘　　要：采用具有良好铸造性能和力学性能的A356合金为研究对象,基于计算机模拟的方法,利用Pro CAST软件对铸件铸造过程中的热裂纹进行了预测,并与实际结果进行了对比分析。结果表明,Pro CAST软件的热裂纹预测结果与实际浇注铸件的热裂纹情况较好吻合;随着杆长度的增加,热裂纹敏感区的热裂纹敏感性逐渐增大。Taking A356 alloy with good casting properties and mechanical properties as research object, the hot crack during the casting process was simulated using ProCAST software, and compared it with the actual results. The results show that the hot crack predicted using ProCAST software are good agreement with which of the actual pouring castings. Along with the increase of rod length, crack sensitivity of casting hot crack sensitive zone is increasing.
