适用于高过载、高旋转弹药的滚转稳定平台有效解决了该类弹药的导航参数测试问题。该平台基于复摆运动原理设计,通过分析内弹道环境下平台的抗过载能力,以及在外弹道飞行过程中平台受力状况,对其内筒运动稳定性的影响,设计了轴向负荷承载区的过载转移装置。建立了平台在弹载环境下内筒运动的微分方程。通过对弹药的气动力仿真,以及系统动力学模型的计算,得到平台内筒滚转角速率与角度变化曲线;并在冲击台与高速飞行仿真转台上进行相应验证试验。试验结果与计算结果对比,表明平台可抗过载10 000g,且弹载环境下内筒作小幅的往复摆动,符合复摆的运动规律,其运动状态稳定。 Rolling stability platform suitable for high overload and high revolving ammunition effectively solves the navigation parameter test problem of such ammunition. The platform is designed based on the complex pendulum movement principle. By analyzing the anti-overload capability of the platform in the internal ballistic environment and the influence of the platform on the stability of the inner cylinder during the external ballistic flight, the design of the axial load bearing zone Overload transfer device. The differential equations of the inner cylinder motion of the platform under the missile loading environment are established. Through the aerodynamic simulation of the ammunition and the calculation of the system dynamics model, the curve of angular velocity and angle of the inner drum of the platform is obtained. Corresponding verification tests are conducted on the impact table and the high-speed flight simulation turntable. The comparison between the test results and the calculated results shows that the platform can resist overload of 10 000 g, and the inner cylinder can swing slightly back and forth under the loading environment, which accords with the movement law of the complex pendulum and its movement state is stable.
