Oldsmobile's Computer Application to V-8 Crankshaft Design 660352

Oldsmobile's Engine Design Group has replaced a lengthy semigraphical crankshaft design balance procedure with a computerized design analysis program for V-8 crankshafts. This paper explains how the computer is used to reduce the time required, human errors, and complexity in crankshaft balance and weight optimization. The design analysis is accomplished by a multisubroutine Fortran IV computer program which results in a complete set of bearing loads with rectangular and polar plots of all bearings, along with the design information for each counterweight and external unbalance.
