Finite Element Analysis of Spindle Assembly of NC Machine Tool and Experiment Validated

摘要

In order to design the machine tool successfully, the analysis and evaluation of the essential parts should be performed after the products designed and before the prototype finished. The spindle and spindle assembly are the essential parts of the NC machine tool. So it is very important to analyze the dynamic-static characteristic of the spindle assembly and to study the effect on machinery function. This paper's research is based on a NC machine tool produced by a certain Plant of Machine Tools. Methods of simulating the spindle assembly support are studied, and the configuration of the spring damper elements of the bearing supports are also studied, and the FEA on spindle and spindle assembly has been made to confirm its dynamic characteristics. Then the FEA models are validated by some experiments.
