导弹发射车主动控制悬架多工况减振研究

Research on Vibration Damping for Missile Launcher with Active Suspensions Under Multiple-loading Case

某车载导弹武器系统拟采用任意点无支撑发射方式,采用主动控制悬架可以使运输发射车重要部位同时满足导弹发射和机动状态的减振要求。对于发射和机动两种工况,分别应用最优控制和自适应控制理论设计控制器,并给出了作动器的切换策略。仿真计算显示该方法有较好的减振效果。

An arbitrary-site support-free launching mode is intended to be taken by some vehicular missile weapon system. The vibration damping requirements of the key section of missile transporter-launcher can be met by using active suspensions for both the launching and maneuvering states simultaneously. By using optimal control and adaptive control theoryies respectively, two controllers were designed for launching and maneuvering states and the actuator switching strategy was also given. The simulation results prove that the method has a satisfactory vibration damping effect.
