Introduction to Analytical Methods for Internal Combustion Engine Cam Mechanisms

Dr JJ Williams was involved in research into flow-induced vibrations of large structures and rotating machinery for 7 years. His best known work from this period is on the Vibration of Cooling Tower Shells. He then spent 18 years as a University Teacher lecturing in a wide range of subjects in Mechanical, Civil and Electrical Engineering. During his last five years as an Academic, his research was centred on analysis of cam mechanisms and valve spring vibration. For a further 18 years he worked as a Design Analyst at Ilmor Engineering, where much of his time was devoted to writing software for the design of valve train components and engine bearings for CART, Indy Car and Formula One. This software was also suitable for other engines and he designed cams for a 1920 Miller Straight 8, together with Rolls Royce Merlin Engines for a P51 Mustang and the Battle of Britain Flight. A more extreme version of these cams was also produced for use in a Mustang for the Reno Air Races. More recently he has worked as a consultant writing programs mainly for the design of valve trains for Formula One, high performance sports-racing cars and motor cycle engines.
