ABSTRACT

Linear guide pairs are the main part of the CNC machine tools. The dynamic behaviours are the main properties of the linear guide. These properties can mainly increase the service life of linear guide pairs. The main propose of this study is the comparison of stiffness of linear guide pairs by FEA and experiment. Measure the stiffness experimentally and, compare the results with FEA to prove the correctness of FEA model. For studying was chosen three linear guides: Chinese company-1, Chinese company-2 and abroad company. The results of this study are (1) Set up the finite element model of linear guides with different geometrical parameters. (2) Comparison of FEA and experiment results shows almost same results. (3) The FEA results show correctness of analysis. These studies are useful for establishing the stiffness on different structures of linear guides.
