Abstract: Vehicular and/or walk behind vibratory compactors utilize a vibrated roller or plate to impose compaction forces on a densifiable strata, such as ground soil, a roadway base material or pavement. Utilizing a rotating energy source, such as a engine or hydraulic motor, to create the vibration appears to have reached its limit in the ability to provide a wide range of vibration frequencies and amplitudes to satisfy the ever increasing demands placed on vibratory compactors. Instead of relying upon rotational energy, the present invention contemplates the use of a linear oscillator to produce the vibrations, and preferably utilizes at least one electromagnet to control the frequency(s) and amplitude(s) of a compacting vibration. The present invention finds potential application in a wide range of vibratory compactors, including walk behind models that utilize a plate and larger vehicular models that include one or more vibrating rollers.
