N2 - The influence of the torque arm position of shock-strut landing gear on the potential seizure phenomenon of the shock absorber is analyzed, and the general calculation formula of reaction force of the piston rod for forward stretching and lateral stretching landing gear is also derived in the paper. Based on above research, the optimization design method of the torque arm position is put forward, which solving the torque arm position to make the piston rod counterforce minimum. Namely, for the optimal design method, the target function is piston rod counterforce, and the design variable is the position of torque arm in relation to the strut of landing gear. Finally, a set of computer programs of the optimal design method are compiled, which has been proved that is totally applicable for the inside or outside wheel of strut and forward or lateral stretching shock-strut gear.
