Dynamic Performance Analysis

The linear rolling guideway is one of the most essential parts of the machine tool. So it is very important to analyze the dynamic-static characteristic of the machine tool by considering rolling guideway for the study of the effect on machinery function. The research is based on a NC machine tool produced by a certain plant of machine tools. In this study, methods of simulating the rolling guideway support were studied; and the configuration of the spring damper elements of the bearing supports were investigated. The finite element analysis on the CKS6125 machine tool was used to confirm its dynamic characteristics. The finite element analysis models were validated by some experiments.

This paper presents the magnetostatic field analysis of a coaxial magnetic gear device proposed by Atallah and Howe. The structural configuration and speed reduction ratio of this magnetic gear device are introduced. The 2-dimensional finite-element analysis (2-D FEA), conducted by applying commercial FEA software Ansoft/Maxwell, is performed to evaluate the magnetostatic field distribution, especially for the magnetic flux densities within the outer air-gap. Once the number of steel pole-pieces equals the sum of the pole-pair numbers of the high-speed rotor and the low-speed rotor, the coaxial magnetic gear device possesses higher magnetic flux densities, thereby generating greater transmitted torque.
