非接触式电磁加载水润滑轴承监测系统

At present, there were some issues (vibration, noise, heat, frictional wear, et al) of traditional mechanical or hydraulic contact loading methods in experimental studies of water-lubricated bearings. In addition, the monitoring system, especially the function of software, was imperfect. All of the issues mentioned above would affect the shafting stability and the accuracy of test results. In order to solve the existed problems, a non-contact electromagnetic loading device (the size and angle of electromagnetic loading force might be adjusted) was designed, a monitoring system was developed based on LabVIEW for water-lubricated bearings, and the film pressure test on water-lubricated rubber bearings was conducted. The results were compacred with simulation ones, and the results show that the running of system is stable, the test data is reliable and the practical effectiveness is well.
