Abstract

The invention discloses a load spectrum loaded knuckle bearing damage evaluation test device, and belongs to the field of bearing measurement. The problem that in the prior art, a test for truly simulating the high altitude environment of a knuckle bearing is lacked is solved. The device comprises a voice coil motor fixedly connected with a knuckle bearing, the voice coil motor is fixedly connected with the knuckle bearing through a linear motion shaft, a displacement sensor is arranged on one side of the linear motion shaft, a load sensor is arranged between the linear motion shaft and the knuckle bearing, and the voice coil motor, the displacement sensor and the load sensor are all connected with a computer control system. According to the invention, a knuckle bearing damage evaluation test under a specific load spectrum is realized, so that the flight condition of a helicopter is simulated more truly.

Description

technical field [0001] The invention belongs to the field of bearing measurement, in particular to a joint bearing damage evaluation test device loaded with a load spectrum. Background technique [0002] A high plateau is a plateau with an altitude of 2,438 meters (8,000 feet) and above. Most of China's Qinghai-Tibet Plateau, Western Sichuan Plateau, Pamirs and Yunnan-Guizhou Plateau are above 4,000 meters above sea level. [0003] The helicopter realizes the control of the flight attitude of the aircraft such as ascent, descent, advancement and hovering through the interaction between the rotor and the air. Therefore, the service reliability of the key components of the rotor system directly affects the overall maneuverability, stability and flight safety of the helicopter. The main rotor knuckle bearing is used to connect the blades and the control system, and is an extremely important key moving part on the helicopter control system and power transmission path. Helicop...
