Abstract: In order to obtain greater accuracy in simulation, more sophisticated models are often required. When it comes to the torsional vibration of reciprocating mechanisms the effect of inertia variation is very important. It has been shown that the inclusion of this variation increases model accuracy for both single-cylinder and multi-cylinder engine torsional vibration predictions. Recent work by the present authors has revealed that piston-to-cylinder friction may modify an engine's ‘apparent’ inertia function. K… Show more

“…Recently, it was pointed out that the inertia of the connecting rod will exert an influence on the piston's secondary motion. 10,11 In a previous paper by two of the present authors, 12 a new model for the piston dynamics was presented by considering the connecting-rod effects. The results show that the new model can predict the performances of the piston dynamics and of the lubrication of the skirtliner system more accurately.…”

“…In order to validate the model the brake power of the Stirling engine was calculated by first establishing the total torque on the crankshaft. Equations obtained from [26] , [27] were used for this calculation. The torque ( Tq ) from the piston and displacer is determined with Eq.…”
