영문 초록

This study is concerned about the development of a three-dimensional bending machine for heat exchanger. Recently, three-dimensional bending is required for various heat exchangers. The purpose of this study is the design of a three-dimensional bending machine by analysis of bending process, structural analysis simulation, and reliability evaluation of the machine by using a laser interferometer. The analysis is carried out by FEM simulation using DEFORM and CATIA V5 commercial software. The copper-tube is modeled by shell elements and the machine is modeled by placing proper shell and solid finite elements and fictitious mass properties to represent the real one. In addition, this machine has attained high accuracy repeatability. In order to improve the accuracy of this machine, the repeatability of feed, rotation, and bending are measured by a laser interferometer. The final results of analysis are applied to the design of three-dimensional bending machine and the machine is successfully developed.
