    摘要: A transmission fluid circuit includes a transmission, a cooler, and a valve. The valve includes a housing, a spool and an actuator. The spool is movable inside the housing between a first position and a second position. The actuator includes a smart material configured to be activated in response to the temperature of the fluid exhibiting at least a first temperature such that the actuator is in a first state. The smart material is configured to be deactivated in response to the fluid being a sufficient number of degrees less than the first temperature such that the actuator is in a second state. The fluid flows from the housing to the transmission and from the transmission the cavity when the spool is in the first position. The fluid flows from the housing to the cooler and from the cooler to the transmission when the spool is in the second position.

    摘要: A method for controlling welding forces of a weld tip to a work piece during a vibration-welding process includes positioning an Active Material (AM) element adjacently to a welding interface, and varying a property of the AM element to regulate the welding force. The AM element may be disposed between the weld tip and a weld face thereof, or between the work piece and an anvil. The property may be varied as a function of heat generated by the welding process. A property of each of a plurality of AM elements may be independently and selectively varied via an energy source, or passively. A vibration welding system includes a weld tip and an AM element connected adjacently to a welding interface. The system regulates a welding force applied by the weld tip to a work piece during the welding process by varying a property of the AM element.

    摘要: Active material actuator assemblies are provided that enable simplified control systems and faster actuator cycle times. A movable member is provided that has multiple active material components operatively connected to it. The active material components are separately selectively activatable for moving the movable member. Movement of the movable member via activation of a first of the active material components triggers activation of the second active material component to further move the movable member. Alternatively or in addition, previously activated active material components are protected from undesired stretching during activation of another active material component or, when desired, an active material component may be reset via activation of another of the active material components in order to prepare it for subsequent activation.

    摘要: A method of reducing an initial stress on a cable includes stretching the cable to a first length to thereby define the initial stress. The cable has a central longitudinal axis, and includes a plurality of wires each twisted around the axis and formed from a shape memory alloy transitionable in response to a signal between a first state wherein each of the wires has a first temperature-dependent length, and a second state wherein each of the wires has a second temperature-dependent length that is less than the first. After stretching, the method includes activating the alloy by exposing the alloy to the signal such that the alloy transitions from the first to the second temperature-dependent state. Concurrent to activating, the method includes elongating the cable to a second length that is greater than the first to define a second stress on the cable that is less than the first.
