The landing gear retraction and retraction mechanism is a key component in the aircraft takeoff and landing process.Research is conducted around the structural form and retraction method of the landing gear,with high safety performance,compact structure,and easy retraction as the design goals.The foldable front three point layout is used as the layout form,and 3D design software is used to model the landing gear retraction and retraction mechanism of the aircraft.The key components of the aircraft landing gear retraction mechanism,such as anti torsion arm,buffer,position lock,and retraction actuator,were designed through theoretical calculations.The motion process of the retraction mechanism was simulated and analyzed to verify its rationality and feasibility.Finally,finite element analysis was conducted on the outer and inner cylinders of the retraction actuator,and the maximum stresses of the outer and inner cylinders were found to be 44.00 MPa and 46.09 MPa,respectively,which were lower than the yield limit of the material and met the design requirements.
