摘要
为了降低导弹行进间发射时车体的强烈振动,提出了利用磁流变阻尼器进行半主动控制的方法。首先,对采用垂直发射方式的导弹发射车悬架系统进行了简化,建立了四自由度振动模型,推导出悬架系统的状态方程。然后分别考虑发射车在恶劣路况下的行驶以及行进间发射2种工况,利用磁流变阻尼器提供控制力进行了线性最优二次型振动控制。最后编写了控制程序并进行了仿真计算。结果表明,实施半主动控制后,2种工况下车身的振动得到了较好的抑制。
In order to reduce the vibration of vehicle during launching,semi-active control using magneto rheological damper is proposed. First,the suspension system of launch vehicle is simplified,and vibration model with 4 degrees of freedom is established. The state equation of the model is set up through selecting the state variables. Then,the situations of maneuvering and launching are considered. The linear quadratic optimal control is conducted and the controller is designed based on magneto rheological damper. Simulations based on the two working situations show that the displacement and acceleration under the two situations are reduced greatly.
