Abstract

The present study aims to combine the fields modal analysis and signal processing and to show the use of Frequency Response Function (FRF), as a vibration transfer path, in enhancing reliability and abilities of the next generation vibration-based rolling bearing condition monitoring (CM) systems in complex mechanical systems. In line with this purpose, the hereby-presented paper employs an appropriate numerical model, that is, Multibody Simulation (MBS) of a vehicle’s drivetrain as a manner for numerical modal and structural analyses. For this, first, the principles of vibration-based bearing fault detection are reviewed and presented. Following that, a summary of MBS modelling and validating strategies are given. Then, the validated MBS model is used as a case study for further investigations. The results can confirm existence of challenges in fault detection of rolling bearings, in particular in complex mechanical systems. In further discussions, the capability of FRFs in fault localization and determination of ideal sensor positions is discussed in some detail. Finally, concluding remarks and suggestions for future works are summarized.

基于多体仿真的结构动力学对滚动轴承故障诊断影响研究

本研究旨在将模态分析和信号处理领域相结合，并展示频率响应函数（FRF）作为一种振动传递路径，在复杂机械系统中提高下一代基于振动的滚动轴承状态监测系统的可靠性和能力。根据这一目的，本文采用了一个合适的数值模型，即车辆传动系的多体仿真（MBS），作为数值模态和结构分析的一种方式。为此，首先介绍了基于振动的轴承故障检测原理。然后，对MBS建模和验证策略进行了总结。然后，将经过验证的MBS模型作为案例进行进一步研究。研究结果可以证实滚动轴承的故障检测存在挑战，特别是在复杂的机械系统中。在进一步的讨论中，详细讨论了FRF在故障定位和确定理想传感器位置方面的能力。最后，总结了结语，并对今后的工作提出了建议。

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
