Numerical investigations on the static stiffness of industrial ball bearing linear guides

Abstract

A technology of creating of geographically distributed multi-operator control of mechatronic devices via the Internet is This research work deals with some numerical investigations on the static stiffness of machine tools ball bearing linear guides. Finite Elements Method (FEM) is employed to carry out the simulations using ANSYS software. Previously, we have conducted some experimental researches of the guide's stiffness in different directions such as radial, lateral and angular directions. As experimental researches cost a lot of time and money, it is necessary to use numerical methods at the design stage and also for further investigations. Therefore, more data are available and the experiments can be concentrated to the most important fields. In this work a FEM model of the guides is developed and the results are compared to the experimental ones. A good agreement has been found to be between the experimental and numerical results.

Experimental and Analytical Investigations on Normal and Angular Stiffness of Linear Guides in Manufacturing Systems

“…Many researchers have investigated on different kinds of guiding systems. Static stiffness and friction behaviour of ball bearing linear guides have been investigated experimentally [6,7]. Some papers have been published on straightness errors of various types of guides [8][9][10][11].…”

Experimental Investigations on Stick-Slip Phenomenon and Friction Characteristics of Linear Guides

“…The role of friction minimization on accuracy enhancement of hydrostatic guideways has been studied [11]. Some researchers have investigated the static stiffness and friction behaviour of translational guides [12]. Some researchers have studied about the influence of friction in machine tools' performance.…”
