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.

The dynamic characteristic of junction surface is an important part of the dynamic characteristics of NC machine tools, and it is sometimes the weakest link of the machine tool's dynamic characteristics. The precision of the finite element calculation of the machine tool's dynamic characteristics shall be affected by the junction surface parameters directly. Linear Motion guide is one of the most widely used components of the NC machine tool, and its characteristic is one of the most important components of the performances of the NC machine tool. The HSR series of linear motion guides are taken as the object of the paper, and its static and dynamic characteristics are studied. And the parameters of static and dynamic characteristics of HSR, such as static stiffness, natural frequency and modal shape are obtained. The accuracy of the finite element analysis mode is verified, which establishes the foundation for the dynamics analysis of machine tool.

The modal analysis and harmonic response analysis of the machine tool table with periodic truss-core structures are analyzed and calculated by finite element analysis software-ANSYS Workbench, then we get the finite element analysis results. After comparing the results with finite element analysis results of the original machine tool table, we come to the conclusion that the dynamic properties of the machine tool table with periodic truss-core structures are better than the original machine tool table’s. It makes a base for optimized design and remanufacturing.

The analysis of spindle static stiffness is particularly important. The concept of spindle stiffness is introduced. Based on software ANSYS, the finite element analysis model of simplified spindle is established. Two equivalent forms of bearings are discussed and the analysis results are compared. The stress distribution nephogram of spindle is given. The research indicates that using spring-damper element instead of bearings is more suitable and the machining accuracy mainly depends on the stiffness rather than strength.

Taking the bed of a large machine tool as an example, static stiffness and modal analysis were studied by the software HyperWorks. Based on the results of the finite element analysis the structural topology optimization of the bed was compiled, with the optimization target is minimum volume of the rib plate and the bed constraint conditions are stiffness and natural frequency. The lightest topology shape of the bed was obtained in the premise of its stiffness and strength which can provide the guidance for the next precise design of the structure. The results showed that the mass of the bed was reduced by 8.58% while the stiffness improved 7.41%.
