Problems solved by technology
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the existing UAV pan-tilt damping device is limited by the parameters of the spring and damper and only has a good absorption of vibrations with a small range of frequencies and amplitudes. effect, so the reduction of the vibration transmitted from the drone fuselage to the gimbal is not effective in many cases

The invention discloses an unmanned aerial vehicle pan-tilt vibration damping device and method, relates to the field of unmanned aerial vehicles. The device comprises a final assembly support and three sets of unit oscillators, and is characterized in that lead screw motors are arranged on lead screw mounting bases with lead screw sliding tables after being connected with lead screws, limiting stators are arranged on limiting stator mounting bases, and deflection positive rods with electron holes in one ends being loaded into deflection positive balls are arranged on vibration motors; the vibration motors are arranged on vibration motor mounting bases, the limiting stator mounting bases are fixed on the lead screw sliding tables, the lead screw mounting bases and the vibration motor mounting bases are arranged on the final assembly support and the deflection positive rods are enabled to be positioned inside the limiting stators to form the unit oscillators, and the three sets of unitoscillators are arranged on the final assembly support and it is guaranteed that the axes of the vibration motors of the three sets of unit oscillators are perpendicular to one another; and an inner chip of an unmanned aerial vehicle is used for controlling vibration damping through feedback controlling of the lead screw motors and the vibration motors. The unmanned aerial vehicle pan-tilt vibration damping device is arranged between the unmanned aerial vehicle and a pan-tilt, and a good vibration damping effect on the vibration with wider frequency and amplitude range on the pan-tilt of the unmanned aerial vehicle is realized.
Description
technical field [0001] The invention relates to the field of unmanned aerial vehicle design, in particular to a vibration reduction device and method for an unmanned aerial vehicle platform. Background technique [0002] In recent years, drones have quickly become a popular research object in China due to their simple and convenient operation, high reliability, simple structure and easy maintenance. Most drone users use drones for aerial photography. UAV aerial photography needs a free motion platform that can carry various real-time transmission cameras and other sensors, that is, the gimbal. big impact. Most of the existing UAV pan / tilt vibration damping devices adopt the principle of spring damping system and are installed between the UAV body and the pan / tilt to absorb the vibration from the UAV body to weaken or cut off the vibration transmission. to the gimbal. [0003] However, the response frequency and response amplitude of the vibration damping device based on t...
