Interactive Visual Modeling and Simulation for Virtual Maintenance of Aircraft Landing Gear

Interactive visual simulation is an important tool in virtual maintenance of aviation equipment. This paper uses the virtual maintenance training of aircraft landing gear as the study object, applying parametric feature modeling technique in UG and in accordance with design requirements the 3D model of aircraft landing gear was established, meanwhile, using the cubic spline interpolation to solve the difficult problem of UG modeling. This paper focuses on using interactive three-dimension visual simulation methods and based on the agent model and its auxiliary model to realize assembly/disassembly process of landing gear. We propose a real-time method is using texture mapping and light render techniques to producing realistic animation. Based on the evaluation were carried out, since the animation is intuitionist, lifelike and didactic in character, it can be used to support the training of maintenance man and reflect the process accurately.
