The electromagnetic hydraulic comprehensive simulation test loading device for the shafting comprises a prime motor and a master control unit, wherein the prime motor and the master control unit are connected with each other through a first coupling; the prime motor is used for supplying power to a test shaft to enable the test shaft to rotate; the rotation speed of the prime motor is controlled by the master control unit; the electromagnetic hydraulic comprehensive simulation test loading device for the shafting also comprises an electromagnetic torque loading device, a hydraulic force loading device, a sensor detection and feedback unit and a hydraulic control unit, wherein the electromagnetic torque loading device generates magnetic force through a direct current to supply torque to the moving test shaft, the hydraulic force loading device comprises a radial force loading device and an axial force loading device, and the sensor detection and feedback unit is used for collecting the torque applied by the electromagnetic torque loading device, force applied by the hydraulic force loading device, and the speed of the test shaft. By adopting the electromagnetic hydraulic comprehensive simulation test loading device for the shafting, which is provided by the invention, the torque, the axial stress status and the radial stress status of the test shaft in a running process can be simulated, 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
