BOW-SHAPED SPRING FOR MARINE VIBRATOR

摘要

A spring member for marine vibrators. At least some illustrative embodiments are bow-shaped spring members including an outer surface, an inner surface; the outer and inner surfaces defining a thickness of the bow-shaped spring member. The bow-shaped spring member further includes first and second hinge members disposed on opposite ends of the bow-shaped spring member; a length defined between the first hinge member and the second hinge member; and a width defined along the first hinge member, the width in a range of from 50% to 150% of the length. The bow-shaped spring member also comprises a contour on the outer surface defined by a perpendicular section through the outer surface along the length, the contour including a medial portion having a curvature with a first algebraic sign; first and second peripheral portions abutting respective first and second hinge members, the first and second peripheral portions having a curvature with the first algebraic sign; and first and second intermediate portions disposed between respective first and second peripheral portions and the medial portion, the first and second intermediate portions having a curvature with a second algebraic sign opposite the first algebraic sign.

1. A marine vibrator comprising:
a shell configured to transmit vibrations to a body of water; a driver coupled between at least one bow-shaped spring member and the shell, the driver is configured to drive vibrations of the bow-shaped spring member; and the at least one bow-shaped spring member is configured to transmit the vibrations to the shell; the at least one bow-shaped spring member comprises:
an outer surface;an inner surface, the outer and inner surfaces defining a thickness of the spring member;first and second hinge members disposed on opposite ends of the bow-shaped spring member;a length defined first hinge member and the second hinge member;a width defined along the first hinge member, the width in a range of from 50% to 150% of the length;a contour on the outer surface defined by a perpendicular section through the outer surface along the length;
the contour comprises:
a medial portion having a curvature with a first algebraic sign;first and second peripheral portions abutting respective first and second hinge members, the first and second peripheral portions having a curvature with the first algebraic sign; andfirst and second intermediate portions disposed between respective first and second peripheral portions and the medial portion, the first and second intermediate portions having a curvature with a second algebraic sign opposite the first algebraic sign.
