A Shafting Electromagnetic-Hydraulic Comprehensive Simulation Test Loading Device

Abstract

The present invention provides a loading device for shafting electromagnetic-hydraulic comprehensive simulation test, which includes a prime mover motor and a main control unit connected to the test shaft through a first coupling. The prime mover motor is used to provide power for the test shaft to make it rotate. The speed of the moving motor is controlled by the main control unit, and it also includes an electromagnetic torque loading device, a hydraulic pressure loading device, a sensor detection feedback unit and a hydraulic control unit; the electromagnetic torque loading device generates magnetic force through direct current to provide torque to the moving test shaft; The loading device includes a radial force loading device and an axial force loading device; the sensor detection feedback unit is used to collect the torque applied by the electromagnetic torque loading device, the force applied by the hydraulic pressure loading device, and the rotational speed of the test shaft. By adopting the device of the invention, it is possible to simulate the torque and axial and radial force conditions of the test shaft during operation, so as to carry out the reliability test of the test shaft.

Description

technical field [0001] The invention relates to a shaft system performance simulation loading test device, in particular to a shaft system electromagnetic-hydraulic comprehensive simulation test loading device. Background technique [0002] At present, with the development of science and technology, the performance requirements of mechanical equipment are getting higher and higher, especially the reliability and service life of large machinery are related to huge economic benefits and personnel safety. It should be required that the working reliability of each mechanism should meet certain requirements, and the shafting is an indispensable key part in many machines. Such as the main shaft of the ship, the rotating shaft of the water turbine and the propeller shaft of the helicopter. When the machine is running, the shaft system, as the transmission structure of the machine, is subject to various internal and external forces, and is prone to deformation, wear, torsion, fract...

AI Technical Summary

Problems solved by technology

At present, there are few types of reliability shafting test platforms, and the simulation of the real working state of the target shaft is not ideal, especially the accurate simulation of the tension, pressure and torque of the shaft is difficult, so it is necessary to develop a Precisely controlled load simulation test loading device
