Improvement on Composite Connecting-Rod Design
The use of composite connecting rod in alternative engines offers noticeable advantages such as inertial forces reductions and high fatigue resistance.
Several studies have shown the possibility to manufacture composite connecting rods satisfying the static load resistance requirement. The past research had been carried out without limitations concerning geometry and dimensions of the conrod.
In this study the Authors use a finite element method on several models of carbo-resin conrod for a two strokes one-cylinder engine which show geometry and dimensions according to the production engine.
Several prototypes have been realized and the theoretical results have been substantially confirmed by the experimental analysis.
