Measuring device for structure transfer characteristics of unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The invention relates to a measuring device for structure transfer characteristics of an unmanned aerial vehicle and the unmanned aerial vehicle. The measuring device comprises a plurality of digital sensors which are respectively fixed to a to-be-measured structure on a fuselage; an installation carrier, which is used for being detachably installed on the fuselage, wherein a processor is arranged on the installation carrier, and the processor is used for calculating the acceleration of the to-be-detected structure according to the vibration signals detected by the digital sensors; and an electric signal transmission assembly,which is made of a flexible material, connects the plurality of digital sensors to the mounting carrier and is electrically connected with a processor. Therefore, the vibration signals of the to-be-detected structure are detected through the digital sensors and transmitted to the processor through the electric signal transmission assembly for data analysis to obtain the acceleration of the to-be-detected structure, and the multiple digital sensors can obtain data at the same time so as to calculate the transfer function and the vibration characteristic of the structure. Therefore, vibration signals at any structural position of the unmanned aerial vehicle in a flight state can be independently acquired, and the digital sensors are flexibly distributed.

Description

technical field [0001] The present disclosure relates to the technical field of unmanned aerial vehicles, and in particular, relates to a measuring device for structural transfer characteristics of an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] During the flight of the UAV, various vibrations and shocks will be generated due to the rotation of the propeller motor and the air flow. Long-term operation leads to structural fatigue and deterioration, and regular structural health inspections of UAVs are required. [0003] In related technologies, cargo drones lack the measurement method of structural transfer characteristics, while the structural health detection of civil aircraft is complicated and the detection device is large, which cannot match the application of drones. At present, the detection of conventional structures uses ground equipment, through wired To connect the sensor and the acquisition system by means of a 220V power ...
