One of the important factors resulting in the performances of the machinery is its dynamic characteristics. The spindle assembly is one of the usual parts of NC machine tool, so its dynamic-static characteristics will affect the performances of machine tool. The study is based on a NC machine tool produced by a certain plant of machine tools. The finite element dynamic analysis model of spindle assembly was developed by introducing two or three groups of circumferential spring damper elements which are arrange at different angle around the spindle, and the effect of different supporting conditions and different arrange angle on the modal analysis of the spindle assembly were discussed. The finite element analysis on spindle and spindle assembly has been made to confirm its dynamic characteristics. Then the finite element analysis models are validated by some experiments.

This paper introduces a optimize design method of ship unloader. The traditional structure design method is totally by experience and manual calculation, while this method is using the Finite Element Analysis (FEA) method to optimize the structure of ship unloader. Therefore this method may keep the stress and deformation of the structure under permission with less use of materials. First we use the FEA analysis software ANSYS to analyze the static strength and stiffness of grab ship unloader, and get its stress and deformation under different work conditions. Then we evaluate the results and modify the structures to improve the performances of the structure under the complex working conditions. Case study shows this method is effective and efficient in practical use.
