摘要： A method for execution by a computing entity includes interpreting an electric response from a set of electric field sensors to produce a piston velocity and a piston position of a piston associated with a head unit device. The head unit device includes a chamber filled with a shear thickening fluid (STF) that includes a multitude of piezoelectric nanoparticles. The method further includes determining a shear force based on the piston velocity and the piston position. The method further includes determining a desired response for the STF based on the shear force, the piston velocity, and the piston position. The method further includes generating an electric activation based on the desired response for the STF and outputting the electric activation to a set of electric field emitters positioned proximal to the chamber.

摘要： A magnetorheological fluid with balanced viscosity and sedimentation properties includes: a magnetic material; a medium to allow the magnetic material to be dispersed therein; a dispersant to disperse the magnetic material within the medium while forming a magnetic material holding structure to hold the magnetic material; and a reinforcing agent to reinforce the magnetic material holding structure. An amount of the magnetic material is 25 wt % to 75 wt % relative to a sum of the medium and the magnetic material. An amount of the medium is 25 wt % to 75 wt % relative to the sum of the medium and the magnetic material. An amount of the dispersant is 0.5 wt % to 6 wt % relative to the sum of the medium and the magnetic material. An amount of the reinforcing agent is 5 wt % to 300 wt % relative to a weight of the dispersant.

摘要： In a fluid-filled cylindrical vibration damping device, an inner shaft member and an outer shaft member are elastically linked by a main rubber elastic body, and fluid chambers in which a fluid is filled are provided to be in communication with each other through an orifice path. The fluid filled in the fluid chambers is a magnetic functional fluid. The fluid-filled cylindrical vibration damping device includes a magnetic unit generating a magnetic field through power conduction. Magnetic path formation members to which the magnetic field is applied by the magnetic unit are arranged on sidewall portions on two facing sides in the orifice path. A magnetic flux concentration part 46 is provided at at least one the magnetic path formation members. A dimension of the magnetic flux concentration part in a length direction of the orifice path is reduced toward an inward side in a facing direction.

摘要： A head unit system for controlling motion of an object includes a set of secondary object sensors and head unit devices that include shear thickening fluid (STF) and a chamber configured to contain a portion of the STF. The chamber further includes a front channel and a back channel. The head unit system further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid flow sensors and a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber.

摘要： A magneto rheological damper includes a housing extending between a first opened end and a second opened end and defining a fluid chamber extending therebetween. An end cap is located at the first opened end and coupled to the housing. A piston is disposed in the fluid chamber dividing the fluid chamber into a compression chamber and a rebound chamber. A piston rod extends along the center axis and attaches to the piston for movement with the piston between a compression and a rebound stroke. A magnetic field generator is located in the compression chamber and in an abutment relationship with the end cap. An extension portion protrudes radially outwardly from the housing and defining a compensation chamber and a channel. The channel is in fluid communication with the compression chamber and the compensation chamber for allowing the working fluid to flow from the compression chamber to the compensation chamber.

摘要： The present invention relates to a movement-dependent stabilisation support system (100) for stabilising a moving body (200), which comprises a plurality of sensors (110), a plurality of actuators (120) and a control unit (130). The plurality of sensors (110) continuously detects movement parameters of the body (200), on which basis the control unit (130) determines whether there is an instability of the body (200). If it is determined that there is an instability, the control unit (130) selects a stabilisation strategy, according to which the actuators (120) are controlled. When controlled, the actuators (120) attached to the body (200) stiffen and limit the freedom of movement of the body (200), such that a movement in the direction of the imminent unstable state is prevented or suppressed. In this way, the body (200) is supported in its stabilisation and an imminent fall is prevented.

摘要： A vibration damping actuator provided by the present disclosure uses a magnet system or a spring system to introduce controllable negative stiffness characteristics into a semi-active system, so as to couple a controllable negative stiffness actuator on the basis of the semi-active actuator (controllable damping actuator). Based on the coupling and integration of the semi-active actuator (controllable damping actuator) and the controllable negative stiffness actuator, the vibration damping actuator may realize four-quadrant mechanical characteristics of an active actuator, improve the vibration damping effect of the semi-active system on the basis of ensuring the advantages of low power consumption, low cost, stability and reliability, and simple structure of the vibration control system of the semi-active actuator (controllable damping actuator), and improve the vibration isolation effect of the semi-active system to a level close to that of an active system.
