摘 要： This study investigates the dynamics of roller bearings by utilizing the dimension theory technique to diagnose the bearing clearance faults of revolving machines. The generation of local defects in rotating machines is closely related to the clearance behavior of the rotor-bearing system. A dynamic model of bearing with dimension theory by matrix method (DTMM) is developed for characteristics of bearing clearance considering the influence of local defects on the inner and outer bearings races. The characteristics of bearing internal radial clearance considering the impact of the defect on the bearing are analyzed. An experimental study has been performed under various operational conditions. The noisy signal is subsequently eliminated using the modulation signal bispectrum (MSB). The efficiency and reliability of the stated approach are evaluated using a specialized bearing test and a run-to-failure fibrizer test. As a result, this technology offers a significant opportunity to execute more cost-effective maintenance work to eliminate the breakdown of machinery.

本研究采用尺寸理论技术，通过诊断旋转机械的轴承间隙故障，探究滚子轴承的动力学特性。旋转机械中局部缺陷的产生与转子-轴承系统的间隙行为密切相关。为此，基于矩阵法的尺寸理论轴承动态模型（DTMM）被开发出来，用于分析轴承间隙特性，并考虑局部缺陷对内、外轴承滚道的影响。同时，对轴承内部径向间隙特性进行了分析，重点考察了缺陷对轴承性能的影响。在多种运行条件下开展了实验研究，随后利用调制信号双频谱（MSB）去除噪声信号。通过专用轴承测试和运行至失效的纤维化测试，评估了该方法的效率与可靠性。结果表明，该技术为开展更具成本效益的维护工作提供了重要机会，从而有效避免机械设备的故障发生。
