Research on on-line monitoring and control system of electromagnetic loading device for water lubricated bearing
Abstract
In order to solve the problem of dynamic electromagnetic force instability of non-contact electromagnetic loading device, an on-line monitoring and control system was designed and developed to provide the accurate load for experimental study of water-lubricated bearing. Firstly, the electromagnetic loading device and water-lubricated bearing test rig, as well as monitoring and control system are introduced. Secondly, the finite element simulation method was used to model and analyze the electromagnetic loading device, and the distribution map of magnetic induction intensity under different currents and speeds was obtained. Finally, the designed monitoring and control system was applied to actual test, and the test and simulation results are compared and analyzed. The analyzing results show that when the current is less than 2 A, the maximum error between the simulation value and the experimental value is only 3.7%, and the system is to be verified stably and reliably.
