Research on Implementation of Parameterized Landing Gear Analysis Model

The landing gear system is one of the key subsystems of the aircraft. It is designed to meet the requirements of small weight, small footprint, high life and reliability, and low life cycle cost. At the same time, the take-off and landing of the aircraft is a high-risk stage of aviation safety accidents. Therefore, the landing gear is an important accessory in aircraft flight safety. The landing gear needs to be associated with various aircraft parameters such as aircraft takeoff weight, engine nacelle size, and aircraft wingspan to meet actual needs. Considering the fact that the traditional design method is time-consuming and low in efficiency, the CATIA software is used as the development platform to build a practical parameterized modelling system. Based on the parameters offered by the aircraft, the model is expected to cooperate with the aircraft in the simulation of the takeoff and landing process and provide the foundation for the further research.
