The High-Cycle Fatigue of a Reciprocating Piston Engine model is based on an example of a three-cylinder reciprocating engine from the Multibody Dynamics Module. In this engine, a flywheel is mounted on the crankshaft, with the assembly supported on both ends by journal bearings. The model also features three sets of cylinders, pistons, and connecting rods that are identical. Hinge joints are used to connect the bottom ends of the connecting rods to the common crankshaft as well as to connect the pistons to the top ends of the rods. A prismatic joint is used to connect each of the cylinders to a piston.
