Device and method for testing tension of unmanned aerial vehicle propeller

Abstract

The invention relates to a device and a method for testing the tension of an unmanned aerial vehicle propeller. The device comprises a sliding structure, sliding rods and a tension detection structure, wherein the sliding structure is connected on the sliding rods in a sliding manner; supporting seats are arranged on the sliding rods; one end of the tension detection structure is connected with the lower end of the sliding structure; one end of the tension detection structure is connected with the supporting seats; the unmanned aerial vehicle propeller is connected to the upper end of the sliding structure; the sliding structure is driven to slide on the sliding rods by the tension generated when the unmanned aerial vehicle propeller works; and the sliding of the sliding structure generates tension on the tension detection structure to obtain the tension of the unmanned aerial vehicle propeller. The magnitude of the acting force is detected by the tension detection structure, and thedistance between a mounting seat and a sliding seat is adjusted in the early stage, so that the distance between two blades of the actual unmanned aerial vehicle propeller is approximately simulated,the safe distance is maintained, tension parameters are accurately obtained, and the structure is simple and the operation is convenient.

Description

technical field [0001] The present invention relates to unmanned aerial vehicle, more specifically refer to the device and method for tensile test of unmanned aerial vehicle propeller. Background technique [0002] UAVs have been widely used in the industry. Markets such as plant protection, wiring, fire protection, and communications have huge demand for resource consumption. Therefore, many companies across the country are designing UAVs. As a designer, you usually need to make reasonable planning for the UAV platform structure in the early stage. Whether the UAV arm adopts a single-axis single-propeller design or a single-axis positive and negative propeller design, because the effects of these two design methods are completely different. No matter which method is used, the UAV motor and propeller are inseparable from the design. Due to technical difficulties and cost savings, motors and propellers are usually purchased from mature products in the market. Whether the pur...

Problems solved by technology

[0003] At present, for the test of propeller tension of single-axis single propeller or single-axis positive and negative propeller, the spring is generally used to drive the sliding base, and the propeller is installed on the sliding base. By calculating the expansion and contraction of the spring and its own elastic coefficient, the propeller pulling force is calculated. However, this structure cannot accurately obtain the tension parameters, and can only estimate approximate values, and it is difficult to ensure that the spring is in the original length state when the propeller is not working, and its test environment is difficult to approximate the actual environment, resulting in inaccurate tests
