Test platform for constant load control performance of electric winch of helicopter

Abstract

The invention discloses a test platform for constant load control performance of an electric winch of a helicopter. The test platform comprises a test platform frame, a helicopter electric winch, a working bedplate and a reel, wherein a tension detection pulley block and a tension sensor connected with the tension detection pulley block are arranged on the test platform frame; the test platform further comprises a tension controller; a signal input end of the tension controller is connected with a signal output end of the tension sensor; the two ends of the reel are respectively connected with two bearing bases on the working bedplate; an output shaft at one end of the reel is successively connected with a magnetic powder clutch, a coupler, a speed reducer and a servo motor; the magnetic powder clutch, the coupler, the speed reducer and the servo motor are all arranged on the working bedplate; a wire rope passes through the electric winch of the helicopter and the tension detection pulley block in turn and is connected into the reel. The test platform provided by the invention has the characteristics of constant load, high loading control precision, safe and reliable structure, easiness in detaching and maintaining and capability of meeting the test demand on the loading performance of the wire rope of the electric winch of the helicopter, and can be widely applied to the field of electric winch test.

Description

technical field [0001] The invention relates to a helicopter test platform, in particular to a helicopter electric winch constant load control performance test platform. Background technique [0002] Helicopter electric winches use electricity as the driving force to lift loads by winding steel cables or cables. At present, it has been widely used in the fields of military, ocean and people's livelihood, and can complete personnel lifesaving, lifting goods and high-altitude operations. The performance of the helicopter electric winch system must be systematically tested after leaving the factory, regular inspection and overhaul. [0003] Since the cable of the electric winch is about 100 meters long, it will be wound on the reel of the test bench in several turns when retracting and unwinding the cable, and the torque transmitted to the reel by the servo motor is constant, because T=F·R (Torque T, tension F, reel diameter R), it is not difficult to see that the change of t...
