摘要
以某型倾转翼无人机为研究对象,分析其过渡段过程中各个部件的运动方式,为使得无人机能够平稳飞行,成功完成过渡阶段,设计出一种以蜗轮蜗杆传动机构为主要部件的倾转装置,蜗轮蜗杆装置传动平稳且能够让倾转翼部分具有自锁效应,使其达到预定位置后不会因受到气动力的影响而发生相对运动,同时也保证了飞机前飞模式的稳定。针对倾转装置运动工况进行有限元仿真分析,并完成蜗轮蜗杆装置的强度分析及寿命预测。结果表明:设计出的装置能够满足现有的强度和寿命要求,其计算结果可为后续的优化提供一定的参考。
Taking a certain type of tilt-wing UAV as the research object,the motion mode of each component during the transition period is analyzed,to enable the UAV to fly smoothly and successfully complete the transition phase,a tilting device with a worm and wormwheel mechanism as the main component is designed.The worm and wormwheel device is smooth transporting power and can make the tilting wing part have a self-locking effect,so that it does not get relative motion due to the influence of air force after reaching the predetermined position,and it will also ensure the stability of the forward flying mode of the UAV.The platform is a tool for analyzing the movement conditions of the tilting device and completing the strength check and life prediction analysis of the device.The analysis results show that the designed device can meet the existing strength and life requirements,and the calculation results can be provide as some reference for subsequent optimization.
