摘　　要：针对微尺度条件下利用离心力矩返回的非自由式擒纵装置缺乏理论计算依据，提出了“类刚度系数”的概念，并据此使用传统非自由式擒纵装置周期公式计算了该机构的平衡摆振动周期，该机构的平衡摆振动周期随驱动力变化，可实现解除保险距离恒定。通过仿真计算得到的振动周期数据与试验数据基本一致，证明提出“类刚度系数”的概念是合理的，同时经过仿真计算得出的距离散布远小于小口径弹道枪的原预留保险距离设计参数12～30m。可认为在不同的弹丸初速下能够保持恒定的解除保险距离。Aiming at of the balance of the struture that the micro-scale conditions non-freestyle escapement device that uses centrifugal torque to return is lack of theoretical calculation basis, the concept of ＂similar stiffness coefficient＂ was put forward, and the vibration cycle of balanced pendulum was calculated with traditional non-freestyle escapement device cycle formula. The vibration cycle of the balance of the structure changed with the driving force, and the arming distance is constant. The cycle calculated through the formula are the same as experimental data basically. The concept of ＂similar stiffness coefficient＂ is reasonable. At the same time, scattered distance through the simulation was far less than design parameters of original reservation safety distance from 12 meters to 30 meters of the small bore bullet. It was considered to be able to maintaining a constant arming distance in different projectile velocity.
