The mathematical model was verified in experiment with the method of indirect squeeze cast Archimedean spiral proof sample. And the experimental results show that the maximum deviation between the theoretical value and measured value is less than 8%.

• 采用间接挤压铸造阿基米德螺旋线试样的方法对该数学模型进行了实验验证,实验结果表明:理论计算值与实验测定值之间的最大偏差小于8%25;
