摘要
将电流变液作为一种可控阻尼介质应用于起落减振器,实现对减振器的主动阻尼控制,减缓飞机降落时的高速冲击。采用理想的飞机减振器模型,建立动力学阻尼控制的数学方程,通过数值计算获得阻尼参数的控制规律以及电流变液电场强度的变化规律,得到了满意的减振器冲击能量减振效果。
This paper aims to apply electrorheological fluid as controllable damping medium to a landing shock absorber to accomplish the active damping control of the shock absorber and alleviate the high speed shock of airplane landing. Using an ideal shock absorber model, the paper established a mathematical equation for dynamic damping control. The control of damping parameters and change of electric field strength were obtained through numerical calculation. Satisfactory results of shock absorption were achieved.
