Automotive Design Calculations

This section presents sample calculations to aid the reader in understanding the calculations behind the development of a fuel cell power system. The sample calculations are arranged topically with unit operations in Section 10.1, system issues in Section 10.2, supporting calculations in Section 10.3, and cost calculations in Section 10.4. A list of conversion factors common to fuel cell systems analysis is presented in Section 10.5 ans a sample automotive design calculation is presented in Section 10.6. 

Modern CAD—an acronym for computer-aided drafting or design—has its roots in the early 1960s. Aerospace, automotive, and electronics companies first used CAD. These large companies were the only ones who could afford computers that could perform the massive calculations needed for CAD. As personal computers became affordable and CAD software became available for this size of computer, CAD became a universal application in design, manufacturing, and construction (see Figure 7-1). 

Stokes, A. 1992. Gear Handbook Design and Calculations. Oxford, U.K. Butterworth-Heinemann. The emphasis on this work is on the calculations portion of the title. This relatively brief volume contains all the formulae necessary to design, manufacture, and inspect a wide variety of gear types. Produced in association with the Society of Automotive Engineers. 

In order to eomplement their knowledge, the engineers who work with structural materials in automotive, aerospace, bonding of metals, plastics, and composites should also, of course, read the chapters Design and calculation of bonded parts , Physics and chemistry of adhesion , Surface preparation before bonding , Metal bonding , Bonding composites , and also Epoxy adhesives , Application equipment , etc.
