P183 Pushing the Vibrator Envelope – How Low Can We Go? Z. Wei* (Input/Output Inc.) J. Sallas (GeoMagic) & G. Tite (Schlumberger) SUMMARY At low frequencies the energy produced from a seismic vibrator is constrained by several mechanical and hydraulic limitations: the reaction mass stroke the hydraulic pump flow the pump response time the servo valve stroke the accumulator size the engine horsepower the peak force-decoupling the harmonic distortion and the vehicle chassis isolation. A model useful for simulating a seismic vibrator dynamics is developed to evaluate the impact of these parameters on the vibrator fundamental force envelope at low
