Abstract
This paper presents the analytical method to evaluate the impact force induced by piston slap considering the dynamic effect of motion and vibration of connecting rod, crank shaft and engine block. The inertia force of connecting rod in vertical , horizontal and rotational direction are taken into consideration and the effects of these inertia forces on the piston impact force are discussed comparing with the conventional simulation method of piston slap. Moreover, influences of piston slap force upon the vibration and main bearing impact force of crank shaft are examined.
