摘要
以国内某四轮无人机为研究对象,在考虑摩擦力、侧向力和角速率等各种因素的情况下,全面分析研究了四轮无人机地面滑跑时的运动特点和受力情况,建立了六自由度刚体飞行器地面运动的动力学方程和运动学方程。在此基础上,对全量非线性模型进行了起飞、着陆时地面运动的仿真,该仿真结果表明了系统模型的正确性。
Motion characteristics of and loads acted on a domestic unmanned aerial vehicle （UAV） with four-wheel landing gear in the ground rolling are investigated allowing for various factors including ground friction, side force, and rotation rate, etc. and the six-degree-of-freedom dynamic and kinematic equations of motion of the rigid vehicle in the ground operation are developed. A ground rolling simulation in the phases of takeoff and landing for the UAV is conducted using the nonlinear model. The simulation results show the validity of the system model.
