This research proposes a novel landing gear system using a four-bar linkage mechanism. The mathematical model of the landing gear system is calculated analytically. A simulation study is performed to investigate the landing gear performance in reducing the impact vibration response of the main system. It is found from the simulation study that nonlinear characteristic of the landing gear stiffness improves its impact vibration response. The simulation results show that rebound displacement and acceleration response of the main system using the proposed technique is smaller than that of using a conventional landing gear system.
