Integration of Manufacturing Design Applications in FE–Based Applied Mechanics Courses Mansur Rastani North Carolina A&T State University

ABSTRACT Many mechanical engineering disciplines are implementing numerical methods of designing mechanical and or structural components within junior or senior–level courses utilizing a technique such as finite element analysis (FEA). However, the classical examples and case problems studied in these courses do not usually provide the students with the erudition about the problems encountered in manufacturing of designed components. This manuscript practices a PC–based approach using algor finite element software to incorporate many of the problems which come from actual applications in various industries into the FEA design of mechanical/structural components. Some of the problems come from aftermarket product refinement, or during product development. It is the purpose of this paper to show how to use FEA from model building to obtaining a solution for these problems.

INTRODUCTION 1 Two rationales could be named for using Finite Element Method (FEM) in product design . First, manufacturing technology is a field that synthesizes the design ideas to produce a valid product using existing tools and/or machinery. However, one has to have the tools and insights to a design in order to effectively synthesize that design into an optimized product. Every bit of a material not necessary for the functioning of a particular product adds to the overall product cost in raw material costs, production costs, shipping costs, and general overhead costs associated with the product. The bottom line for any product is cost and profitability. Second, Often problems encountered in everyday practical applications do not lend themselves to closed–form or analytic solutions. This complication is found in almost every area of manufacturing design from tool and automotive industries to military, aerospace, consumer medical, and recreational products to mention a few. Consequently, the product designer is forced to make approximations based on similarity to classical, or closed–form soluble problems which result in overdesigned product that may be non–competitive from a cost standpoint. On the other hand, the product designer may rely on physical prototyping which is generally expensive and increases the cost of the design process. With the proliferation of personal computers and the availability of software to aid the design process, it is no longer necessary to rely heavily on intuition and settle for approximate solutions to real–world problems. 2 Finite Element Method is a numerical analysis procedure to obtain solutions to these many complex problems posed in various areas of the manufacturing environment in order to produce the optimum product: a product that performs as intended, meets all of the specified environmental requirements, and is the least costly 3 to produce. A good FEM software interfaces with a variety of CAD programs. The interface allows a rapid design and analysis cycle of the model.
