Abstract: 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.

摘要： 在水润滑轴承试验研究中，传统机械或液压等接触式加载方式存在振动、噪声、发热与摩擦磨损等问题，另外，监测系统特别是软件功能还不完善，影响轴系稳定运行与测试结果准确性。针对上述问题，设计了非接触式电磁加载装置（电磁加载力大小及角度均可调节），并基于LabVIEW开发了水润滑轴承监测系统；应用该系统对水润滑橡胶轴承进行水膜压力测试试验，并将试验结果与仿真结果进行对比，结果表明，系统运行稳定，测试数据可靠，实用效果良好。
