摘要滚动轴承是现代机械中最常见的部件之一，但人们对其在工作和振动条件下的特性知之甚少。因此，当主轴系统的设计和他们的动态刚度是很重要的，它是很难找到合适的特性用于建模。这是本文的目的，以说明为什么这些特性是难以衡量的，并讨论了文献中的结果。这也是非常少的模型已经开发出代表的刚度和阻尼的滚动轴承的情况。在20世纪80年代，一些模型被开发出来，但这些都是在机密，发行量有限的出版物。然而，现在已经允许在公开文献中介绍这些模型。描述了在旋转条件下测量滚动轴承刚度和阻尼特性的装置原理。提出了一种理论分析，可以预测的滚动接触的特性。此外，还分析了使用轴承时产生的必要接头的影响。详细描述了钻机及其初始校准和测试。所获得的广泛结果在本工作的第2和第3部分中描述。
Abstract Rolling-element bearings are among the most common components of modern machinery and yet little is known about their characteristics under working and oscillating conditions. Thus, when spindle systems are designed and their dynamic stiffness is important, it is very difficult to find suitable characteristics to use in the modelling. It is the purpose of this paper to indicate why these characteristics are difficult to measure and to discuss the results that are available in the literature. It is also the case that very few models have been developed to represent the stiffness and damping of rolling-element bearings. In the 1980s, some models were developed, but these were in confidential, limited-circulation publications. However, permission has now been given to present these models in the open literature. The principles of a rig are described that allow the stiffness and damping properties of rolling-element bearings to be measured under rotating conditions. A theoretical analysis is presented that allows the characteristics of the rolling contacts to be predicted. In addition, the effect of the necessary joints that arise when using bearings is analysed. A detailed description is given of the rig and its initial calibration and testing. The extensive results obtained are described in parts 2 and 3 of this work.
