This work has been developed within the framework of non-stationary rotating machinery surveillance with emphasis on the detection of rolling element bearing defects. The numerical models proposed in this paper are based on an "angular" approach which introduces explicitly the machine's free body rotation degrees of freedom allowing simulations in non-stationary operating conditions. In a previous work, a deep groove ball bearing model has been presented considering the rolling resistance phenomena, allowing to describe the angular speed variations due to the bearing dynamics, a phenomenon that has been detected experimentally. In this work, a classic gear mesh description together with the rolling element bearing defects model have been used to build a wind turbine virtual machine. The model is used as a device to test Instantaneous Angular Speed spectral indicators. (C) 2019 Elsevier Ltd. All rights reserved.
本研究是在非稳态旋转机械监测框架下开展的，重点在于滚动轴承缺陷的检测。本文提出的数值模型基于“角”方法，明确引入了机器自由体的旋转自由度，从而能够模拟非稳态运行条件下的系统行为。在先前的研究中，已提出一种深沟球轴承模型，考虑了滚动阻力现象，可描述由轴承动力学引起的角速度变化，这一现象已在实验中被验证。在本研究中，结合经典齿轮啮合描述与滚动轴承缺陷模型，构建了一个风力涡轮机的虚拟模型。该模型被用作测试瞬时角速度谱指标的装置。（C）2019 Elsevier Ltd. 保留所有权利。 |
