CFI's Driven Pile Academy: Hosted by the PDCA

EccentricMoment – termused to describe the effectiveness of a force to produce rotation about an axis. It is the value in inch-pounds equal to the weight of the eccentricmultiplied by the distance from the center-line of gravity to the center-line of rotation, thenmultiplied by the total number of eccentrics used in themachine. The size of the eccentricmoment affects the driving force, attainable amplitude, operating frequency, and power requirements for the exciter. Amplitude – the vertical movement of the total vibrating system, and the direct result of the applied force generated by the rotating eccentrics. Aminimumof ¼” amplitude should be achieved when sizing a vibratory hammer for a job.
