    摘要： A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.

    摘要： A method for increasing and/or modulating the yield shear stress of an electrorheological fluid includes applying a sufficient electric field to the fluid to cause the formation of chains of particles, and then applying a sufficient pressure to the fluid to cause thickening or aggregation of the chains. An apparatus for increasing and/or modulating the transfer or force or torque between two working structures includes an electrorheological fluid and electrodes through which an electric field is applied to the fluid such that particles chains of particles are formed in the fluid and, upon application of pressure to the fluid, the chains thicken or aggregate and improve the force or torque transmission.

    摘要： A vibration damping device is mounted between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. A cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with an outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to another portion of the vehicle. A fluid transfer duct is formed between the housing and piston and provides communication between fluid subchambers formed on opposite sides of the piston within the piston chamber. An electrode is attached to either the housing or piston for applying a voltage across the duct to affect the rheological response of an electrorheological (ER) fluid flowing therethrough to provide a controllable mechanism to modify the damping force characteristics of the device. Each end of the piston rod is slidably supported by a slide bushing assembly which is mounted within an end of the housing. The slide bushing assemblies are separated from the ER fluid contained in the fluid chamber by elastomeric seals to reduce bushing wear and deterioration of the ER fluid.

    摘要： A vibration damping device for mounting between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with the outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to the other portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid transfer duct between fluid chambers formed on opposite sides of the piston within the piston chamber. A plurality of spaced metal electrode bands are mounted on an inner surface of the outer housing and are electrically isolated therefrom and communicate with the fluid transfer duct for applying voltages across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device. Certain of the electrode bands may be formed with a plurality of circumferentially spaced, longitudinally extending splines and intervening grooves, which grooves align with splines and grooves formed in a dielectric insulating sleeve mounted adjacent the fluid transfer duct.
