摘　　要：利用MAGMAsoft软件进行仿真模拟,并结合实际生产验证分析了不同浇注工艺下气缸盖变形量及趋势。结果表明,浇注工艺是影响气缸盖变形的主因之一。平浇工艺下铸件变形趋势呈现"两端凸、中间凹",立浇工艺下铸件变形趋势呈现"两端凹、中间凸"。两种浇注工艺下,气缸盖变形整体在1.5mm以内,满足生产需求。The MAGMAsoft software has been used for simulation and combined with actual production verification to analyze the deformation and trend of the cylinder head under different pouring processes.The results show that the pouring process is one of the main factors affecting the deformation of the cylinder head.The deformation trend of castings under the flat pouring process is"convex at both ends and concave in the middle",and the deformation trend of castings under the vertical pouring process is"concave at both ends and convex in the middle".Under the two pouring processes,the overall cylinder head deformation is within 1.5mm,which meets the production requirements.
