Abstract


Torque arm is an important part of the telescopic landing gear, preventing the relative rotation between piston rod and cylinder, to ensure that the wheel is working properly. Based on the torsion stress analysis, the topology optimization theory of SIMP interpolation was adopted to investigate the force analysis of torque arm by virtue of shape optimization module of ANSYS Workbench. The results indicate that the optimized structure can meet the requirement in practice, while the weight reduction of torque arm was up to 16.7%. This research is of great value and significance for aircraft weight range.
