Title
(EN) Energy dissipating elastomer damper
Abstract
(EN)

An energy dissipating elastomer damper comprises a generally hollow housing member having an interior aperture of a predetermined cross section. A first closure member is attached to one end of the housing and has an axial aperture and a second closure member is attached to the other end of the housing and has an axial aperture. A compressible resilient elastomer member is disposed within the interior aperture of the housing. A force transmitting member is disposed for axial movement within the compressible resilient elastomer member and has at least one spherical force transmitting portion of a predetermined shape disposed intermediate a first end extending through the axial aperture of the first closure member and a second end extending through the axial aperture of the second closure member. A force applied to one end of the force transmitting member causes compression of the compressible resilient elastomer member around the force transmitting member thus providing a resistance to movement thereof and absorbing and dissipating the energy of the applied force. The resistance to movement remains constant during the entire range of the travel.
