| Abstract: | 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. |
