Abstract: This paper will explore the applications of advanced software such as ScanIP and the +FE module (Simpleware Ltd.,Exeter UK) and COMSOL multiphysics software in reinventing an existing part in the absence of original design data. It showcases the reverse engineering workflow of going from a 3D computed tomography (CT) scan of an automotive engine manifold to a COMSOL simulation ready, multi-part computational fluid dynamics (CFD) or finite element (FE) mesh of the segmented geometry. It discusses the effectiveness of applying multiphysics software in reverse engineering practice with a focus on the applicability of Simpleware and COMSOL in three-dimensional (3D) image-based modeling, structure analysis and functionality evaluation.
1. Introduction
During the past decade reverse engineering has become a common and acceptable practice utilized by the aftermarket suppliers to provide comparable substitutes for the OEM (Original Equipment Manufacturer) counterparts in many industries, such as the automotive industry. Recently many OEMs have also started to utilize 3D image-based reverse engineering in their development of new versions of vintage parts to shorten the turn-around time. For example, a significant amount of research time can be saved while developing a more efficient automotive clutch if reverse engineering is used to build the design data base from an existing clutch geometry.
