Modal Analysis and Experimental Analysis of Dynamic Characteristics of Linear Rolling Guide

Article Preview

Abstract:

The finite element model of the liner rolling guide of the CNC machine tool is established. Then the natural frequencies and the corresponding vibration modes of the liner rolling guide (LRG) are obtained by analyzing the finite element model (FEM) of the linear rolling guide in two different boundary conditions. By comparing the modal characters of the two states it is proved that the movable joint and bolted interfaces of the rail have certain effects on the dynamic performance of linear rolling guide. Besides, the liner rolling guide also have been tested dynamically, obtaining the modal parameters of the rail guide; finally, the validity of finite element model and the effect of boundary conditions on the interface of the linear rolling guide are verified by comparing the finite element analysis of frequency and experimental analysis of frequency
