A rubber spring device is formed by alternately laminating a plurality of layers of hard plates whose linear dimension W in a direction parallel to the longitudinal direction of each equalizer bar is shorter in plan view than a linear dimension H in a direction parallel to an axle direction, and rubber layers. The rubber spring device is disposed between an end portion of each equalizer bar and a center axle in an articulated dump truck, and is allowed to function as a suspension. Thus, even when the rubber spring device is deformed into an accordion shape, peak positions of an internal stress within each rubber layer can be dispersed and reduced, thereby preventing generation of cracks within each rubber layer.

Vibration damper

Номер: US20130309097A1
Автор: David Miller
Принадлежит: Rolls Royce PLC

Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes. It is also possible to provide a tube formed from a shape memory alloy which will expand of its own right in location to engage the hollow cavity wall surfaces for energy absorption during vibration episodes.

Автор: Andreas Skolaude

An electric drive for a processing tool, in particular for a rivet setting appliance, has an electric motor connected to an actuating element that is linearly displaceable in an axial direction. A damping element that acts in the axial direction is arranged between the electric motor and the actuating element for impact decoupling of the electric motor from the actuating element. As a result, sudden loads, for example if a rivet mandrel breaks during the blind rivet setting operation, are absorbed in a material-conserving manner.

A fender for fending a ship from a mooring wall comprises a hydraulic cylinder and piston assembly arranged so that compression of the fender is translated into a force to move the piston in the cylinder. Valves couple the hydraulic cylinder to reservoir that is at least partially filled with gas.

When the force drops away, a return valve allows hydraulic liquid to return to the cylinder, causing the piston to move to expand fender, following movement of the ship away from the fender. In this way oscillating motion is reduced. A plurality of such fenders may be combined with mooring cable holding devices with a similar mechanism that pays out cable when the movement of the ship from the mooring wall cause the force on the mooring cable to grow.
