Experimental Validation for the Performance of MR Damper Aircraft Landing Gear

The landing gear of an aircraft serves to mitigate the vibration and impact forces transmitted from ground fuselage. This paper addresses magneto-rheological (MR) damper gear, which provides high shock absorption efficiency excellent stability in various conditions by adjusting damping force using external magnetic field intensity. performance MR was verified through numerical simulations drop tests that satisfied aviation regulations for gear. In this study, a prototype test jig, two-degree-of-freedom model were developed verify damper, with real-time control, light Two semi-active control algorithms, skyhook hybrid applied carried out under multiple conditions, results compared based on mathematical model. It experimentally as increased, gear’s cushioning significantly improved 17.9% over achieved existing passive damping.
