Simulation and Optimization for Tilt-rotor Rotating Mechanism Based on COMSOL

Abstract

Rotating mechanism is an important part of the tilt-rotor unmanned aerial vehicle (UAV), it plays a crucial role in the transition flight phase and even hover flight. The mechanical performance of the rotating mechanism affects directly flight safety and reliability of the tilt-rotor. In order to study the work process of rotating mechanism, and to find more suitable rotation modes, the rotating mechanism of tilt-rotor is set for the research object. A simulation model is built by using the finite element methods, and through the study of change regulation of speed, displacement, stress distribution and deformation, the movement process of rotating mechanism was made clear. Finally, material selection and structure design of the mechanism was optimized based on the simulation results.
