Straightening and Precision of Guide Rail Characteristics Based on Load-Stroke Deflection Relations Using FEM Simulation

Abstract:

Straightening process is to achieve the best standard and improve geometric quality of products caused by heat treatments and internal structural changes. The straightening of the guide rail was analyzed using the load-deflection straightening model. In this paper, three dimensional FE simulation of the reverse bending and straightening of the steel bar conducted as part of the research to numerically investigate for the mechanical engineering applications are presented. This paper is focused on the straightening precision of the guide rail and springback prediction using finite element method. According to the experimental results, by using numerical simulation with finite element analysis (FEA), the relationships among the maximal loading stroke and straightening stroke with the cross-section shape will be gained, and also the result curves were discussed qualitatively. The appropriateness of the simulation procedures employed in this work is represented for similar condition that is a good agreement between the finite element method and experimental results.
