Authors Abstract
Content
The application of the Stiller-Smith Mechanism for use in an internal-combustion engine is investigated. The dimensionless stroke-to-bore and stroke-to-gear diameter ratios are used as a design vector. The effect of changes in the design vector upon parameters including mechanical efficiency, internal gear loads, bearing reaction forces, and connecting rod loads is investigated. A composite objective function is defined in which these parameters have variable weighting. An optimal design can be reached by using this function. Characteristics of the mechanism with and without the effect of inertial forces are investigated. Results are presented including three-dimensional sensitivity plots and an optimal design.
