摘要：
为深入研究水润滑轴承带载工况下的特性，设计一种非接触式电磁加载装置，并通过理论计算、建模仿真与试验相结合的方法对该装置性能进行研究。首先，介绍电磁加载装置结构与原理，建立该装置等效磁路图，并基于麦克斯韦电磁理论推导出电磁加载力方程；然后，建立电磁加载装置三维有限元模型，对仿真结果进行分析；最后进行水润滑轴承加载试验，将电磁力仿真、理论及试验结果进行对比分析。研究结果表明，磁感线在加载盘底部最为密集，电磁加载装置漏磁很少，电磁力仿真值与实际值最大误差为10.7%，证明该装置合理。

Abstract: In order to deeply study the characteristics of water-lubricated bearing under loading condition, a non-contact electromagnetic loading device was designed, and its performance was studied by theoretical calculation, modeling simulation and test. Firstly, the structure and principle of device are introduced, the equivalent magnetic circuit diagram of device is built, and the electromagnetic loading force equation is derived based on maxwell's electromagnetic theory. Then, the three-dimensional finite element model of device is established and the simulation results are analyzed. Finally, the loading test of water-lubricated bearing is carried out, and the results among electromagnetic force simulation, theory and test are compared and analyzed. The results show that the magnetic induction line is concentrated at the bottom of loading plate, the magnetic flux leakage of electromagnetic loading device is least, the maximum error of electromagnetic force between simulated value and actual value is 10.7%, and the rationality of the device is verified.
