摘　　要：通过对一典型薄壁筒体铸件精密成形时的充型压力曲线仿真分析,优化出最佳的随截面变化的非线性压差曲线,实现了金属液在型腔中的平稳充型,最终获得的筒体铸件质量良好。The filling pressure curve of a typical thin-wall cylinder casting in exactitude forming was analyzed by numerical simulation, the optimized non-linear differential pressure curve with the change of cross-section was obtained, which realized that the molten metal filled the mold in calm state. The results show that the cylinder casting is high-quality.
