Abstract
The purpose of this paper is to present a numerical model predicting shock response of a rotating-shaft spindle motor with nonlinear FDB. The paper consists of the following three parts: 1) the first part is an effective way to represent nonlinear FDB load characteristics; 2) the second part of the paper is to integrate the nonlinear FDB model with an existing spindle vibration model to predict nonlinear spindle response; 3) the third part of this paper is to demonstrate the numerical model through use of two numerical examples
