Abstract
An energy dissipation system for limiting forces applied to object; includes a piston rod that extends out of a pneumatic cylinder which contacts the object, the piston rod is forced from its initial position against a return spring and air is forced into an air line. The force transmitted to the object is consumed by an energy transformation device that responds to the air in the air line. [One such energy transformation device as an air accumulator, which is coupled to the air line trough a check valve. An orifice or release valve, releases air up a predetermined flow rate so that the linear motion of the protected object is transformed into work, which is dissipated.] [Another] The energy transformation device consists of an air-driven motor coupled to a heavy flywheel [through] that is driven by the motor. [A third alternative energy transformation device consist of a second dissipation cylinder and piston, where the dissipation cylinder is coupled to the air line so that the air in line, drives the pistons against a return spring that orifice or release valve, may also be coupled to the airline on to the dissipation cylinder.]
