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.
本研究运用智能算法和实验数据来探究轴承的动态温度。为角接触球轴承创建了一个测试装置，以精确测量两个轴承的温度，并同时独立控制转速、轴向载荷、径向载荷和润滑剂含量。研究利用基于 SKF 轴承的摩擦温度模型，分析了在不同运行条件下轴承的稳定温度。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。研究将通过 SKF 模型获得的结果与实际温度进行了比较。遗传算法显示出更高的准确性和稳健性。经过评估，确定这两种智能方法都适用于处理变量数据输入。本文介绍了一种使用统计数据分析来计算轴承温度的智能方法，这种方法无需分析动力学、热力学或润滑原理。该方法能够在无需边界条件或限制条件的情况下计算瞬态温度，这使其具有极高的通用性。这一特性使其成为轴承设计和温度控制方面极具价值的工具。 |
