In some examples, a shock absorption bracket includes one or more damping pads coupled to a facing surface of an absorption leg. The absorption leg is attached to a support leg and defines an internal corner with the support leg. The support leg is configured to attach to an equipment cabinet. The shock absorption bracket may be configured to define a gap between the damping pads and one or more support surfaces of the equipment cabinet. The shock absorption bracket may be configured to attach to a rear section of an equipment cabinet having an equipment access in a front section of the equipment cabinet.

A snubber gap measurement tool and a method for measuring snubber gaps in resilient mounts are provided. The tool has a handle, a stem, and a flag, and is sufficiently thin to fit within a resilient mount's inspection window. Upon rotation by 90 degrees the tool's flag extends within the snubber gap and thereby allows measurement of the snubber gap.

The invention provides an acoustic material structure and an assembly method of the acoustic radiation structure. The acoustic material structure comprises acoustic units which can be attached onto surfaces of acoustic radiation structures. Each acoustic unit comprises a thin sheet, an air cavity between the thin sheet and the surface of the sound radiation structure, and openings penetrating through the acoustic unit with one end connected to the cavity. The openings can reduce the spring effect of the fluid medium in the cavity, so that the acoustic units attached onto the surface of the sound radiation structure can provide low-frequency sound insulation effects. The acoustic unit may also include support bodies, mass blocks, and constraint bodies. The working frequencies of the acoustic unit can be regulated by the support bodies, mass blocks and constraint bodies. The acoustic material structure can effectively suppress sound radiation from low- and middle-frequency sound waves which have relatively larger wavelength under costs of small weight and space. Moreover, the acoustic material structure can enhance the exchange rate of the heat from the attached structure surfaces by the vibration of the thin sheet.

A steering damper assembly includes a cylindrical pressure tube defining a working chamber; a piston assembly disposed in the working chamber; a reserve tube extending circumferentially around the pressure tube and defining a reservoir chamber that is radially between the reserve tube and the pressure tube; a base valve fluidly connecting the working chamber and the reservoir chamber; and a piston rod fixed to the piston assembly. The reserve tube includes a cylindrical portion and a bulged portion. The cylindrical portion extends concentrically around the pressure tube. The bulged portion includes a first circumferential section and a second circumferential section, the first circumferential section having a maximum radial distance at most equal to an inner radius of the cylindrical portion, and the second circumferential section having a maximum radial distance greater than the inner radius of the cylindrical portion.

A vibration damping device (1, 10, 100) includes a tubular metal bracket (20, 120), a first attachment member (12, 112), a second attachment member (11, 23, 111), an elastic body (13, 113), a partition member (17, 117), and a diaphragm (19, 119). A fixed portion (11g, 23c, 111c) fixed to a fixing portion (20b, 120b) of the metal bracket is formed in the second attachment member. A gap (S2, S21) is provided between a portion of an outer circumferential surface of the second attachment member except for the fixed portion, and a portion of an inner circumferential surface of the metal bracket except for the fixing portion, and a second seal portion (22, 123) is provided between the fixed portion and the fixing portion.

A can bodymaker includes a housing assembly, a drive mechanism, a ram assembly, a domer assembly, and a ram body dampening assembly. The ram assembly includes an elongated ram body. The drive mechanism is operatively coupled to the ram assembly so that the drive mechanism imparts a reciprocating motion to the ram body. The ram body dampening assembly is disposed adjacent the ram body path of travel. The ram body dampening assembly includes a housing and a dampening member. The dampening member is disposed immediately adjacent the ram body path of travel.
