Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0049] Such as figure 1 As shown, the tilting mechanism dynamics optimization method of the tilting rotor UAV of the present embodiment specifically includes the following steps:
[0050] Establish the mechanical-electrical-wind multi-physics coupling multi-body dynamics theoretical model of the tilting mechanism, and analyze the force, moment and motion characteristics of the tilting mechanism during the tilting process;
[0051] Through the multi-physics simulation based on finite element, analyze the change law and influence of the relevant physical quantities of the tilting mechanism, and revise the theoretical model;
[0052] Based on the establishment of the theoretical model and the correction of the theoretical model by multi-physics simulation, an experimental platform for the tilting mechanism is built to verify the theoretical model...
