Environmental simulation vibration test system for unmanned aerial vehicle in real flight state

Abstract

The invention relates to an environment simulation vibration test system for an unmanned aerial vehicle in a real flight state, and the system comprises the unmanned aerial vehicle, a simulation cavity, an environment control system, and a data processing device. The environment control system comprises a controller, a temperature simulation device, a humidity simulation device and a wind power simulation device, wherein the temperature simulation device, the humidity simulation device and the wind power simulation device are controlled by the controller to adjust the temperature in the simulation cavity, the humidity in the simulation cavity and the wind power flow direction and magnitude in the simulation cavity. By the adoption of the system, the environment simulation vibration test system under the actual flight state of the unmanned aerial vehicle accurately simulates the real environment, and therefore accurate test data are obtained.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an environment simulation vibration test system under the actual flight state of the unmanned aerial vehicle. Background technique [0002] In recent years, multi-rotor drones have been widely used in aerial photography, agricultural plant protection, security emergency and other fields due to their excellent operational performance, vertical take-off and landing, hovering and ultra-low-altitude flight. The vibration characteristics of multi-rotor drones are one of the important indicators for evaluating the overall performance of drones, which will have a negative impact on the accuracy of aerial drone imaging and the uniformity of pesticide spraying by plant protection drones. Therefore, the vibration test for multi-rotor UAV is an essential step to study the mechanical performance of UAV. [0003] At present, there are the following defects in the vibration test of dro...

AI Technical Summary

Problems solved by technology

[0004] 1) A complete test system has not been formed, and most of the tests are a temporary test platform built with existing equipment;

[0005] 2) Most of the vibration tests are done under static conditions, and the obtained data cannot accurately reflect the vibration response of the UAV in the actual flight state;

[0006] 3) It cannot simulate complex environmental factors, such as the influence of wind, temperature and humidity on the vibration of drones, etc.
