| 现有测试水润滑轴承特性重要表征参数水膜压力的诸多方法中，由于传感器距离真实测点较远或对轴系创伤较大等原因，导致准确的水膜压力实证数据难以获取，制约了轴承进一步研究与发展。针对上述难题，提出将薄膜传感器嵌入到轴承轴瓦中，而压力数据通过无线传感传输的全新监测方法。首先，建立轴瓦开槽轴承的物理模型，通过对沟槽附近轴瓦变形的有限元分析确定开槽位置、结构与数量；建立轴承流体域和固体域物理模型，对水膜压力分布进行仿真分析；然后，提出薄膜传感器标定方法对其准确标定；最后，进行多工况轴承水膜压力测试试验并与仿真结果和现有方法进行对比分析。研究结果表明，通过在轴承轴瓦开槽嵌入薄膜传感器并进行数据无线传输的方法可行，水膜压力实测数据与仿真结果偏差低于10%，比现有方法实测数据更精确。水膜压力沿轴向递减，轴承内部存在部分润滑膜，处于混合润滑状态。 |

| Existing test water lubrication bearing characteristics of the important characterisation parameter water film pressure of the many methods, because the sensor distance from the real measurement point is far away, or trauma to the shaft system is large and other reasons, the accurate water film pressure empirical data is difficult to obtain, restricting the bearings of further research and development. In response to these challenges, a new monitoring method is proposed in which thin film sensors are embedded in bearing shingles, while pressure data are transmitted via wireless sensing. Firstly, the physical model of axial tile grooved bearing is established, and the location, structure and number of grooves are determined by finite element analysis of axial tile deformation near the grooves; A physical model of the bearing fluid domain and solid domain is established to simulate and analyse the water film pressure distribution; Then, a thin film sensor calibration method is proposed to calibrate it accurately; Finally, a multi-operating condition bearing water film pressure test experiment is carried out, it is compared and analysed with the simulation results and existing methods. The results of the study show that it is feasible to embed a thin film sensor in the groove of the bearing shaft tile and transmit the data wirelessly, and the measured data of water film pressure deviates less than 10% from the simulation results, which is more accurate than the measured data of existing methods. The water film pressure decreases along the axial direction, and there exists a part of lubrication film inside the bearing in a mixed lubrication state. |
