Analysis of the static behavior of a new landing gear model based on a four-bar linkage mechanism

Abstract

A landing gear model using a four-bar linkage mechanism is proposed in this study. The simulation study was conducted to evaluate the effect of the link dimension variation and coil spring constant on the equivalent stiffness and static deflection of the landing gear. The simulation results show that increasing the landing gear dimension affects the static deflection of the landing gear. However, the linear stiffness of the landing gear system is not much affected by the landing gear dimension variation. Furthermore, the landing gear stiffness characteristic is nonlinear for large landing gear displacement.
