Paper Abstract

In this paper, a new measurement apparatus is designed, constructed and tested. This apparatus is placed in the middle of the circular tube and is suitable for use in the experimental determination of the tube curvature and the ovalization of the tube cross-section. In our experiment, two LVDTs, which are connected with the rotating sprockets of the bending machine, is also used for measuring the magnitude of the tube curvature. The comparison of the amounts of the tube curvature measured by the LVDTs and by the new apparatus is also considered in this study. Due to slight influence by the end condition of rotating sprockets, it is believed that the new apparatus yields the more accurate measurement of the tube curvature than the curvature obtained by the LVDTs.
