A numerical study on rotating-shaft spindles with nonlinear fluid-dynamic bearings

IEEE Transactions on Magnetics, 2005
The purpose of this paper is to present a numerical model predicting the shock response of a rotating-shaft spindle motor with nonlinear fluid-dynamic bearings (FDBs). The paper consists of three parts. The first part is to modify an existing linear spindle vibration model to include arbitrary FDB nonlinearity.

Milling Cutter Wear Monitoring Using Spindle Shaft Vibration

Journal of Manufacturing Science and Engineering, 1997
With the intent of continuously monitoring cutting tool condition in intermittent machining operations in a benign manner, a noncontacting measurement system was assembled to measure spindle shaft torsional vibration. Spindle vibration was measured using an optical system and analysis of it in the frequency domain resulted in a measure of spectral ...

Dynamic Modeling of Aerostatic Spindle With Shaft Tilt Deformation

Journal of Manufacturing Science and Engineering, 2019
Abstract This paper presents a new dynamic model of aerostatic spindle including the journal and thrust bearings. Reynolds equations are used to model the dynamics of a 4-degree-of-freedom (DOF) aerostatic journal bearing and a 3-DOF aerostatic thrust bearing. Finite element model of the spindle shaft is developed based on the Timoshenko

Dynamic Analysis of Slender Shaft in Twin-Spindle Turning

Applied Mechanics and Materials, 2011
Machining slender workpiece is still a technical difficulty. This paper investigates the dynamic behavior of a slender shaft subject to constant feedrate moving cutting forces in twin-spindle turning process. The Euler-Bernoulli theory is used to model the rotating shaft.
