AI Technical Summary

Technical Problem

During heavy-load testing, the existing drone tension torque load test platform has excessive swing force due to the swing of the blade, severe wear of the step shaft, easy to damage the bearings that measure torque, poor data consistency, and unable to effectively simulate the real flight status.

Method used

A high-reliability drone heavy-load performance test platform for matrix multi-tension sensors is designed. Through the matrix distribution of four first sets of first tension pressure sensors, the bearing seat can move up and down to reduce vibration, the transmission shaft is 90° with the second tension pressure sensor, and the bearing sleeve on the crossbar is in point contact with the second tension pressure sensor, eliminating torque, and ensuring that the transmission shaft can slide and rotate freely in a small range.

Benefits of technology

Improve measurement accuracy, reduce vibration and wear, ensure data consistency, simulate real flight status more accurately, and reduce the failure rate and maintenance costs of the test platform.

Abstract

The invention discloses a matrix type multi-tension sensor high-reliability unmanned aerial vehicle heavy load performance test platform, and relates to the field of test devices.The test platform comprises a test frame connecting plate, the top of the test frame connecting plate is provided with a fixing seat, and the top of the fixing seat is provided with four groups of first tension and pressure sensors; the four groups of first tension and pressure sensors are distributed at the top of the fixed seat in a matrix manner, and bearing seats are mounted at the tops of the first tension and pressure sensors. Torque is indirectly measured by measuring tension, the transmission shaft and the second tension and pressure sensor form an angle of 90 degrees, the bearing sleeve on the cross rod is in point contact with the second tension and pressure sensor and impacts a contact plate on the second tension and pressure sensor, and the bearing eliminates the torque brought by the transmission shaft through rotation. The second tension and pressure sensors are only subjected to single tension, the torque generated by operation of the unmanned aerial vehicle is calculated through the torque M = F * L, and the four first tension and pressure sensors are distributed in a matrix mode and share the tension jointly.
