Laser radar passive vibration damping device for large-load unmanned aerial vehicle

Abstract

The invention relates to the technical field of structural vibration control, in particular to a laser radar passive vibration damping device for a large-load unmanned aerial vehicle. The device comprises an unmanned aerial vehicle support, a fixed lifting ring, connecting columns, a connecting plate, a rubber shock absorber, a load mounting plate and a laser radar, wherein the unmanned aerial vehicle support is connected with the load mounting plate through the plurality of connecting columns, the upper end of each connecting column is connected with the unmanned aerial vehicle support through the fixed hanging ring, the lower end of each connecting column is connected with the load mounting plate through the rubber shock absorber, and the laser radar is arranged on the load mounting plate. According to the device, a suspension structure is adopted, the mounting space is sufficient, the disassembly is convenience and the like; and in combination with the vibration damping device structure, in the actual work of the unmanned aerial vehicle, the installation of portable load such as the laser radar is facilitated, the working performance range is improved, and meanwhile, the reliable working performance requirement can be met.

Description

technical field [0001] The invention relates to the technical field of structural vibration control, in particular to a laser radar passive vibration reduction device for a large-load unmanned aerial vehicle. Background technique [0002] UAV is a powered, controllable, unmanned aircraft that can carry a variety of equipment to perform a variety of tasks, and has a variety of structures such as fixed wings, single rotors, and multi-rotors. By carrying a variety of loads, UAVs can realize Antarctic scientific research investigation, aerial photography, ground disaster assessment, aerial surveying and mapping, traffic monitoring, public safety, fire rescue, artificial rainfall enhancement, pesticide spraying and other applications. For large-load UAVs, the engineering field of their application often requires the UAV to withstand a large vibration response, and the severe vibration response will affect the working performance of the load that can be carried.

Problems solved by technology

[0005] In view of the above problems, the object of the present invention is to provide a laser radar passive vibration damping device for large-load drones to solve the problem that the drone can carry loads under actual vibration conditions during the working process of large-load drones. To bear the problem of large vibration response, weaken the vibration response transmitted to the load that can be carried by the UAV. The structure of the vibration damping device can effectively reduce the vibration response and provide a large installation space for the load that can be carried by the UAV.
