Abstract: The objective of this research is to enhance and develop analytical and experimental schemes to study the source and path analysis of piston slap noise and to develop tools to relate the piston slap to the engine block vibration. These computer tools solve the piston dynamics and the engine block vibration. The results of this approach are block vibrations that are comparable to experimental results. For validation of the analysis results, a series of experimental tests were conducted on a V8 engine. The results obtained from FEA analysis correlates with the experimental results.

Keywords: piston slaps; engine block vibration; compliance cylinder bore; cylinder bore vibration; FEA; finite element analysis; vehicle vibration; vehicle noise; piston dynamics; V8 engines.
