Kinematic parameterization of Alfa-Stirling crank mechanism

This article considers Alfa-Stirling crank mechanism kinematic parameterization. The obtained equations of a piston and displacer movement with equal connecting rods and with the 90° angle between cylinders axels are presented. The equation of piston movement dependence on the displacer movement does not include the angle of crankshaft rotation. This allows obtaining a numerical model that excludes crank and connecting rods modeling, thus reducing resource intensity of numerical calculations.
