The Use of Calculation Software In Undergraduate Machine Elements Instruction Robert L. Mott University of Dayton Dayton, Ohio

Abstract Education in the principles and practices of the design of machine elements inherently involves numerous topics such as gears, shafts, bearings, keys, clutches, brakes, springs, and many more. Furthermore, each topic requires students to perform extensive calculations to specify design parameters and to analyze the performance of a proposed design. The design of each component must address the interfaces with mating components. Many alternative designs must be considered to work toward the optimum system. Accomplishing these tasks within a typical undergraduate course or curriculum places heavy demands on students and instructors in terms of time limitations and the ability to manage the process. The use of calculation software can facilitate this process and allow students to produce more robust designs. This paper will outline the advantages of employing industry-standard calculation software within undergraduate curricula on mechanical design. The presenter is the author of a popular textbook on machine elements in mechanical design as well as two others in applied fluid mechanics, and applied strength of materials. Over 30 years of experience in writing technical textbooks gives a good perspective on the movement of state-of-the-art technology from research and industry sources into effective undergraduate curricula. The new 4th edition of the author’s book Machine Elements in Mechanical Design, published by the Prentice Hall Company in Upper Saddle River, New Jersey, includes the new MDESIGN software from the German company, TEDATA, designed for use in the United States. TEDATA is the producer of the successful European software MDESIGN mec. Introduction The design of machine elements inherently involves extensive procedures, complex calculations, and many design decisions. Data must be found from numerous charts and tables. Furthermore, design is typically iterative, requiring the designer to try several options for any given element, leading to the repetition of design calculations with new data or new design decisions. This is especially true for complete mechanical devices containing several components, as the interfaces between components are considered. Changes to one component often require changes to mating elements. Use of computer aided mechanical design software can facilitate the design process by performing many of the tasks while leaving the major design decisions to the creativity and judgment of the designer or engineer. Education in the principles and practices of the design of machine elements inherently involves numerous topics such as gears, shafts, bearings, keys, clutches, brakes, springs, and many more.
