Dresser Waukesha has designed a new connecting rod for implementation on the VHP series of natural gas engines. The connecting rod design process was driven by feature based solid models which were readily accessed for finite element structural analysis, rapid prototyping, and production tooling procurement in order to minimize the overall development time. The main objectives of the design effort were higher speed/power rating capability and assembly compatibility with existing 8.50 inch and 9.375 inch bore field engines in both a lean burn and rich burn operating condition. This paper discusses the advanced utilization of finite element analysis and bench testing techniques to expedite the design and test validation process.
