Mechanical system of scientific research and teaching test stand of four-rotor unmanned aerial vehicle

Abstract

The invention discloses a mechanical system of a scientific research and teaching test stand of a four-rotor unmanned aerial vehicle. The core of the mechanical system is that the four-rotor unmannedaerial vehicle, which can do motions by multiple degrees of freedom, is converted into the unmanned aerial vehicle test stand which can only do a rolling motion by a single degree of freedom; the mechanical system comprises the four-rotor unmanned aerial vehicle and an aluminum profile stand; the four-rotor unmanned aerial vehicle part is composed of propellers, a brush-less motor, pipe clips, a carbon fiber pipe, upper and lower central plates, a central shaft, an angle coder and a coder bracket, wherein one end of the carbon fiber pipe is fixedly connected to the central plates by virtue ofthe pipe clips and bolts, and the other end is connected to the brush-less motor by virtue of the pipe clips and bolts; the propeller is arranged on the brush-less motor; the central shaft is fixedlyconnected to the lower central plate; the central shaft is fixedly connected to the aluminum profile stand by virtue of an aligning bearing device; and the aligning bearing device is composed of a vertical bearing seat and an aligning bearing. The aluminum profile stand is defined by connecting a plurality of 30*30 aluminum profiles by virtue of angle pieces, T-shaped bolts and nuts / with the application of the test stand, the most urgent problems in researches of current multi-rotor unmanned aerial vehicles can be solved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a four-rotor unmanned aerial vehicle test bench for scientific research and teaching. Background technique [0002] Human beings are born with the dream of flying, and the research on rotorcraft has a long history. Non-coaxial twin-rotor helicopters are researched earlier among modern helicopters. At present, the United States has the most solid research accumulation in the field of non-coaxial twin-rotor helicopters. Although there are many companies in our country that are developing rotor drones, the core technology is not innovative, most of them are profiling designs, and it is difficult to know the specific parameters of the mathematical model, which leads to the inability of in-depth and innovative research, theoretical research and engineering. Practice is seriously out of touch, and emerging theories cannot be verified by experiments to judge their correctness and...
