CPC G01V 1/135 (2013.01) [B06B 1/12 (2013.01)] | 25 Claims |
1. An improvement for a vibroseis source system, wherein the vibroseis source system has a base plate component, and a reaction mass component which is mechanically isolated from the base plate component via an actuating piston internal to the reaction mass component, the actuating piston being configured to drive vertical displacement of the reaction mass component during vibroseis source system operation when the base plate component is coupled against a surface of earth, the improvement comprising one or more dampers, each damper having at least a first end and a second end, a first end of each damper being directly mechanically connected to the reaction mass component and a second end of each damper being mechanically connected to a frame component of a vehicle on which the vibroseis source system is carried without isolators therebetween, thereby providing mechanically compliant coupling between the reaction mass component and the frame component of the vehicle, wherein the one or more dampers are separate and apart from the actuating piston, wherein the one or more dampers do not add energy to the vibroseis source system, and wherein the one or more dampers transfer inertial mass from the vehicle frame to the reaction mass component.
