摘　　要：气冲造型过程紧实时间短,因此气动系统紧实机构的仿真计算对解的精度要求很高,根据对比常用的数值计算方法即欧拉法、改进欧拉法和四阶龙格-库塔法,本文最后采用四阶龙格-库塔法将数学模型进行离散化并加以求解。Air impact molding process of tight time is short,therefore there is a high requirement for the accuracy of the solution on the aerodynamic simulation system of compact mechanism calculation,according to the comparison of commonly used numerical calculation method,namely Euler method,the improved Euler method and four order Runge Kutta method,Finally mathematical model is discretized and solved by using the four order Runge Kutta method.
