摘要： A carrier mounted seismic vibrator system that is primarily adapted for generation of high force, high frequency seismic energy into an earth medium. The apparatus includes first and second vibrators (12F and R) as supported by first and second lift systems (28F and R) disposed in tandem juxtaposition generally centrally in said vehicle (10), and the lift systems (28F and R) are designed to maintain equal hold-down force on the vibrator coupling baseplates (32F and R) without exceeding the weight of the carrier vehicle. The juxtaposed vibrators are then energized in synchronized relationship to propagate increased amounts of higher frequency seismic energy into an earth medium.

摘要： A high pressure seal is formed between a stationary piston and a reciprocating cylinder. The seal includes a sleeve which has an inner diameter dimensioned to permit the cylinder to slide freely over the piston rod, the sleeve being in rigid contact at one end to the cylinder and the other end to an end plate surrounding the piston and closing the end of the sleeve. A bleeder port communicates with the outer surface of the piston rod, through the piston rod, and terminates at a low pressure supply. Bleeder grooves are formed around the inner wall of the sleeve. A first bleeder groove is positioned in the inner wall of the sleeve at the mid-stroke position of the piston with second and third bleeder grooves positioned at each extreme position of the piston stroke in the inner wall of the sleeve. A plurality of pressure drop grooves is formed along the inner sleeve diameter such that the hydraulic fluid passing from the cylinder into the sleeve will gradually drop in pressure as it moves toward the end plate. Pressure relief at the end plate seal is provided by the hydraulic fluid accumulating in the bleeder grooves where it is removed through the bleeder port.

摘要： A lightweight rigid housing and baseplate structure for a seismic transducer. The baseplate (12) includes a central hub (26) for receiving a lower piston rod (76). Upper and lower skin plates (32 and 36) extend radially outward from the central hub (26). A plurality of equally angularly spaced reinforcing plates (40) also extend radially outward from the hub (26) and have their upper and lower edges rigidly connected to the upper and lower skin plates. A housing assembly (78) rigidly connects an upper piston rod (74) to the baseplate (12), and includes a frusto-conical section (82). The lightweight rigid housing (78) and baseplate (12) structure provides a seismic transducer having in-phase force distribution over substantially the entire area of the baseplate as it is engaged with the earth.

摘要： The present invention relates to a seismic transducer for generating waves in an elastic medium and is particularly applicable to the generation of low frequency shear waves. The transducer is comprised of a mass member having more than one parallel hydraulic cylinder disposed therein, a piston member disposed in each cylinder, each piston member including a piston and a pair of oppositely extending rods, and a frame interconnecting the ends of the piston rods which frame has a base surface thereon for engaging a surface of the elastic medium in energy coupling relationship. A system of hydraulic fluid bleed-back ports associated with the piston members serve to aid lubrication and keep high pressures off of the rod end seals. The present construction permits total enclosure of the mass member and plural piston member assembly.

摘要： An underwater vibrator apparatus for generating a shear wave into the consolidated seabed has a housing, a horizontally mounted mass attached to said housing for movement along an axis substantially parallel to the surface of the earth and hydraulic apparatus for oscillating the mass along the axis. Substantially all of the vibrator housing comprises a sidewall and a bottom. The sidewalls and bottom form a wedge-shaped surface means with an angled surface of the wedge-shaped surface transverse to the movement of the mass, such that as the mass oscillates the underwater vibrator against the consolidated bottom, the vibrator will settle into the bottom. The vibrator will, however, maintain contact with the bottom even when the consolidated bottom is yieldable under vibrated weight.
