Abstract
A seismic vibrator has a baseplate composed at least partially of a composite material. The baseplate has a body composed of the composite material and has top and bottom plates composed of a metallic material. The top plate supports isolators for isolating the vibrator's mass and frame from the baseplate. Internally, the composite body has a central structure to which couple stilts for supporting the mass and a piston for the vibrator's actuator. A lattice structure surrounds the central structure. This lattice structure has radial ribs extending from the central structure and has radial ribs interconnecting the radial ribs.
Claims31
A seismic vibrator, comprising:
- a baseplate at least partially composed of a composite material;
- a mass movably disposed relative to the baseplate and imparting vibrational energy thereto;
- an actuator coupled to the mass and moving the mass relative to the baseplate;
- and
- a controller communicatively coupled to the actuator and controlling operation of the actuator.
A baseplate for a seismic vibrator having a mass component, an actuator component, and a frame component, the baseplate comprising:
- a core body disposed on the seismic vibrator and imparting energy to the ground, the core body composed of a composite material and comprising:
- a central structure to which the mass and actuator components of the seismic vibrator couple;
- and
- a lattice structure surrounding the central structure, the lattice structure having main ribs extending from the central structure and having interconnecting ribs interconnecting the main ribs.
A baseplate for a seismic vibrator having a mass component, an actuator component, and a frame component, the baseplate comprising:
- a core body composed of a composite material and having a top and a bottom;
- one or more upper plates disposed on the top of the core body and supporting the mass component, the actuator component, and the frame component;
- and
- a bottom plate disposed on the bottom of the core body.
