摘　　要：通过实际计算比较了松驰因子w对铸造充型过程模拟软件中所使用的超松驰迭代法的计算速度的影响,并与英国伯明翰大学所做的标准验证实验对比以验证模拟精度.在综合比较了速度和精度的影响后,确定了最佳松驰因子w的取值范围在0.5～0.8.The computational speed of slack factor. It has been verified that tests in Birmingham University, UK. precision, the range of the best slack casting mold filling process was compared with and without considering the present computational results are matched very well with benchmark After the comprehensive comparison of the computational speed and the factor should be ranged within 0. 5-0. 8.
