论述基于磁流变阻尼器的半主动振动控制的一般方法,针对某榴弹发射器后坐缓冲系统的设计要求,建立了缓冲系统的数学模型,对发射器的后坐过程进行了动力学仿真。提出了一种基于设计目标的加权计算方法,通过参数化设计,并计算控制因子D,找到阻尼器的最佳弹簧刚度系数和可控阻尼系数匹配,满足了后坐力和后坐行程的设计要求,为缓冲装置用的磁流变阻尼器的设计提供依据;进行了ADAMS与Simulink的联合控制研究,对比了外加开关(on-off)控制算法和PID控制算法时的控制效果,为磁流变阻尼器的电流控制提供了指导。
The general method of semi-active vibration control based on magnetorheological damper is discussed. According to the design requirements of a grenade launcher recoil cushioning system, a mathematical model of the cushioning system is established and the recoil process of the launcher is simulated. A weighted calculation method based on design goals is proposed. Through parametric design and calculation of control factor D, the best spring stiffness coefficient and damping coefficient of damper are found, which meets the design requirements of recoil force and recoil stroke. The design of magnetorheological damper for buffering device is provided, and the joint control of ADAMS and Simulink is studied. The control effect of on-off control algorithm and PID control algorithm is compared. The current control provides guidance.
