This study used intelligent algorithms and experimental data to investigate the dynamic temperature of bearings. A test rig was created for angular contact ball bearings to measure the temperature of two bearings precisely while independently controlling rotational speed, axial load, radial load, and grease content. The study analyzed the steady temperature of bearings under different operating conditions using a friction temperature model based on SKF bearings. The bearings temperature was computed using traditional backpropagation neural network (BPNN) and genetic algorithms (GA). The study compared the results obtained through the SKF model and the actual temperature against those produced methods. GA displayed a higher level of accuracy and robustness. Upon evaluation, it was determined that both intelligent methods are suitable for processing variable data input. This article presents an intelligent approach to computing bearing temperature using statistical data analysis, which does not require analyzing dynamics, thermodynamics, or lubrication principles. The method's ability to compute transient temperature without boundary conditions or constraints makes it highly versatile. This feature renders it a valuable tool for bearing design and temperature control.
本研究利用智能算法和实验数据，对轴承的动态温度进行了探究。为角接触球轴承设计了一套测试装置，可精确测量两个轴承的温度，并独立控制转速、轴向载荷、径向载荷及润滑脂含量。研究采用基于SKF轴承的摩擦温度模型，分析了轴承在不同运行条件下的稳态温度。轴承温度通过传统的反向传播神经网络（BPNN）和遗传算法（GA）进行计算。研究将SKF模型结果与实际温度以及其它方法所得结果进行对比，结果表明，遗传算法具有更高的准确性和鲁棒性。经评估，两种智能方法均适用于处理可变输入数据。本文提出了一种基于统计数据分析的智能轴承温度计算方法，无需涉及动力学、热力学或润滑原理的分析过程。该方法无需边界条件或约束即可计算瞬态温度，具有极高的通用性。这一特性使其成为轴承设计和温度控制中的宝贵工具。 |
