Abstract


The mechanical impact phenomenon emerges in fast-moving mechanical systems when some of the moving elements reach critical positions.

The first section of the present paper is concerned with the dynamics of the impact between a freely moving bar and a fixed plate.

In the second section, we set out to investigate the impact phenomenon's effect on the dynamic response of an actuation mechanism on an internal combustion engine. Our research study addressed a crank connecting rod mechanism to which we considered a radial clearance in the joint that links the connecting rod to the piston. Under these conditions, during the operation of the mechanism develops an impact that influences the kinematic parameters that define the movement of the two bodies in contact.
