“…Otherwise Qoj=Fcj, that is δo,j=(Fcj/Ko) 2/3 . The conditions in which the ball loses contact with the inner/outer raceways were based on [8] The determining of Hertz's contact stiffness Km (m=i,o) is based on [9] with the consideration of the change in bearing element dimension due to temperature increase. After establishing the contact load and the contact angle, the radial and axial stiffness on the inner and outer raceway can be determined through Hertz's contact stiffness as:…”

In order to avoid the failure of machine tools spindles in the real machining process due to an increase in temperature, it is essential to predict its thermal behavior in the designing phase. The characteristics of machine tools significantly depend on the thermal-elastic behavior of the spindle. These parameters directly affect the productivity and quality of machining operations. This paper presents a thermal - elastic model of the machine tool spindle which was based on the quasi-static model of bearings and the finite element (FE) model of the spindle shaft. Based on quasi-static model of bearings with angular contact, heat generated and thermal contact resistances (TCR) are determined for each position of the balls. The aforementioned constraints have been applied to the 3D FE model of the spindle which allowed for establishing non-stationary change of temperature and thermal deformation. In order to prove the efficacy of the proposed model, experimental measurements of spindle and bearing temperatures were done using thermocouples and thermal imager.

“…The results were then validated by experiments. Based on calculated heat generation in [3,4], Zivkovic et al [5] used finite element ANSYS software to simulate temperature field determining thermal deformation and preload in traditional spindle. Applying ANSYS software for establishment of finite element thermal model of the high speed spindle to analyze temperature and thermal deformation was introduced [6,7].…”

A combination of finite element and conjugate gradient methods to establish an inverse method for estimating heat sources as well as temperatures of a micro high speed motorized spindle is presented in this article. The proposed method is simple in constructing the direct problem by using COMSOL software. Experiment setup and measurement process are introduced. Results show that inverse solutions agree with experimental data based on temperatures at only one measurement point. Influence of speed on heat sources and temperatures is indicated. Temperature distribution in the spindle is also given and discussed. From these findings, it can be said that the proposed method is appropriated for inversely determining the heat source in micro high speed motorized spindle. The obtained results provide useful information to estimate thermal deformation.

“…The finite element method (FEM) is applied to analyze thermal and thermal-structure coupling in [3]. Zivkovic et al [4] presented a model based on bearing model and FEM to consider non-stationary change of temperature and preload. A monitoring thermally induced preload in spindle bearing was presented in [5].…”
