Modeling of vibratory pile driving

3 BASIC COMPONENTS OF A VIBRATORY HAMMER The vibratory hammer, in its most common form, consists of pairs of eccentrically mounted masses which are contained in a frame whose appreciable mass may be called the oscillator. A bias mass iso-lates the oscillator from the hammer support – usu-ally a crane line. The oscillator is separated

Reciprocating Vibratory and Impact-Vibration Hammers

Like the impact-vibration hammer, it was capable of high blow rates, if not a great deal of energy for each blow. The concept was presented to Vulcan in 1977-8; however, the company was going through a generational change, this compounded by the demands of the existing air/steam line (the 6300 was being designed and produced at

Vibration

Vibration (from Latin vibrāre ''to shake'') is a mechanical phenomenon whereby oscillations occur about an equilibrium point.Vibration may be deterministic if the oscillations can be characterised precisely (e.g. the periodic motion of a pendulum), or random if the oscillations can only be analysed statistically (e.g. the movement of a tire on a gravel road).

Fundamentals of the vibratory driving of piles and sheet piles

Vibratory driving is a common method for installing or extracting piles and sheet piles as well as for deep vibratory compaction. The most important parameters are vibration frequency, vibration amplitude and eccentric moment. These parameters govern vibratory driving and, in particular, the soil resistance at the toe and along the shaft of a pile.
