System and method to transfer inertial mass

An improvement for a vibroseis source system, the improvement comprising:

• in a vibroseis source system having a base plate component, two or more vertical Lift Columns extending between a vehicle and the 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 configured to drive vertical displacement of the reaction mass component when the base plate component is lowered and coupled against a surface of earth via the two or more lift columns during vibroseis source system operation:
• a damper mount member extending laterally from at least a first of the two or more lift columns of the vibroseis source system to at least a second of the two or more lift columns;
• and
• one or more dampers, each damper having at least a first end and at least a second end, wherein each first end of each damper is directly mechanically connected to the reaction mass component, and wherein each second end of each damper is directly mechanically connected to the damper mount member without isolators therebetween, thereby providing mechanically compliant coupling between the reaction mass component and a frame component of the vehicle through the damper mount member and through the two or more lift columns, 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.
