为实现车载炮弹丸自动化装填,设计了一种自动推弹装置。以输送122 mm口径弹丸为例,建立三维模型并应用ADAMS进行动力学仿真,得到相应的动力学曲线和运动规律。通过对仿真结果与物理样机实测的比较,验证了虚拟样机的建立具有可信度,证明该自动推弹装置在不同射角下均能稳定推弹,弹丸在强制推弹行程内姿态稳定,能够准确地达到强制推弹行程末端速度和卡膛速度,验证了自动推弹装置设计是合理的。自动推弹装置可以保证推弹的可靠性与一致性。
In order to realize the automatic loading of the on-board projectile and projectile, an automatic pop-up device is designed. Taking the delivery of 122 mm projectile as an example, a three-dimensional model is established and the dynamic simulation is carried out using ADAMS. The corresponding kinetic curves and motion rules are obtained. Through the comparison between the simulation results and the physical prototype, the establishment of the virtual prototype is verified to be credible, which proves that the automatic projectile device can stably propel the projectile at different angles of incidence. The projectile can stabilize within the force of the projectile projectile Accurately to force the end of the projectile stroke speed and the muzzle velocity, proves the automatic push device design is reasonable. Automatic pop-up device can ensure the reliability and consistency of pop-up.
