摘　　要：针对使用ADAMS软件进行火炮发射动力学仿真时,火药气体压力的加载过程繁琐且仿真计算时间和火药气体压力变化不同步等问题,提出了一种基于ADAMS自定义函数的发射动力学仿真方法,使火炮发射时的内弹道过程与制退后坐运动同时在ADAMS软件内部进行动力学求解。从经典内弹道方程和火炮发射时后坐部分的受力分析的基础上,应用位移、速度等函数添加了动力学分析中所需的载荷,采用传感器与脚本控制仿真过程,进行了某122 mm火炮的发射动力学仿真,验证了该仿真方法的准确性。该仿真方法将弹丸运动、火药燃气生成和后坐部分运动相互关联,使其在同一软件内进行求解,可提高仿真计算效率。Aiming at problems of during using the software ADAMS to simulate gun launching dynamics,loading process of propellant gas pressure being cumbersome and simulation calculation time being not synchronized with change of propellant gas pressure,a launch dynamics simulation method based on ADAMS self-defined functions was proposed to synchronously solve interior ballistic process and gun recoil motion inside ADAMS during gun launching.Based on the classical interior ballistic equation and the force analysis of recoil part,the load needed in dynamic analysis was added with displacement,velocity and other functions,and the simulation process was controlled by sensors and scripts.The launching dynamic simulation was done for a certain 122 mm artillery to verify the correctness of the simulation method.It was shown that the proposed simulation method can make motion of projectile,generation of propellant gas and motion of recoil part be related to each other,the three problems can be solved within the same software to improve the efficiency of simulation calculation.
