Simulation of a Series Double Cavity Buffer on the Landing Gear

Abstract

Adopting high performance buffer is the foundation of the landing gear on the helicopter. Based on established models on Adams/Aircraft, a novel type of series double cavity buffer on the landing gear is investigated by dynamic simulation. Corresponding simulation and analysis are achieved, which is helpful for farther structure optimization. It is shown that compared with single cavity buffer, the series double cavity buffer can reduce effectively the acceleration, vertical force and tire force of the landing gear. Under the same condition, vertical force and tire force of the landing gear increase with the initial pressure increase of the high pressure grade buffer in the series double cavity buffer.
