ABSTRACT:
A flexible wall spring damper including opposed first and second rigid mounting members interconnected by a flexible side wall is provided. A spring damper chamber is included within the flexible wall and is interposed between the opposed rigid mounting members. A plurality of elastomeric particles are included in the damper chamber. A selectively pressurizable gas chamber is interposed between the rigid mounting members and the flexible side walls. In one embodiment of the invention, a flexible diaphragm connected to one of the rigid mounting members defines the selectively pressurizable gas chamber. In another embodiment of the invention, a spiral tube defines the flexible side wall and includes an inner chamber including the plurality of elastomeric particles. Relative movement between the opposed rigid mounting members operates to stress the flexible side wall and the plurality of elastomeric particles, and vary the volume of the selectively pressurizable gas chamber. The invention exhibits the operational characteristic of a constant natural frequency independent of the mass supported by the device.
