为研究闭锁力对火箭弹发射的影响，采用发射动力学仿真的方法，在Adams中建立火箭炮的动力学模型，分别仿真不同闭锁力下火箭弹的发射过程，得到火箭弹速度、转速和角位移等曲线。根据仿真结果，分析闭锁力对火箭弹初始扰动和射击密集度的影响。研究结果表明，闭锁力对火箭弹炮口速度和炮口转速影响微弱，是引起初始扰动的主要因素，在满足闭锁性能要求的情况下应尽可能减小。

In order to investigate the effect of lock force on rocket launching, using the method of launch dynamics simulation, the dynamics model of rocket launcher is built in Adams,launching process with different lock forces is simulated respectively,and the curves of speed, rotational speed and angle displacement of rocket are got. The effect of lock force on initial disturbance and firing dispersion is analyzed according to the simulation results. The research result shows that the effect of lock force on muzzle velocity and muzzle rotational speed is very smal, but it is the main factor inducing the initial disturbance. In order to meet the lock require￣ments,the lock force should be reduced as much as possible.
