Abstract

The invention provides an axial force testing system of a high-temperature rotor system. The system comprises a rotating shaft (1), a base (2), an electromagnetic device (3), a displacement disc (4),a sensor mounting base (5), a radial bearing (6), a displacement sensor (7), a temperature sensor (8), a current sensor (9), a power amplifier (10), a control system (11) and a PC (12). The high-temperature rotor system axial force test system provided by the invention adopts a non-contact measurement mode, bidirectional axial force can be measured after one-time installation, meanwhile, the testdevice does not introduce extra interference to the rotor system, and the service life is relatively long.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and testing and control, and in particular relates to a high-temperature rotor system axial force testing system and testing method. Background technique [0002] The axial force of the rotor system is one of the key parameters required to evaluate the structural strength, bearing life, working condition, etc. In some rotor applications where the axial force is dominant, such as heavy vertical rotors, axial flow compressors, aero engines, heavy gas turbines, etc., it is very important to accurately obtain the axial force of the rotor for system performance and life evaluation. [0003] At present, there are mainly direct and indirect methods for the measurement of the axial force of the rotor system in the industry (Ma Qianrong, Wu Hu, Guo Xin. "Axial Force Measurement and Application Research of Core Machines", Measurement and Control Technology, 2013, 23(6), 39-42). The direct method...
