SWITCHABLE/VARIABLE RATE ISOLATORS USING SHAPE MEMORY ALLOYS

摘要

A number of variations may include a product including a variable rate vibration isolator that may include a shape memory material having at least two physical states, wherein each physical state may have a corresponding vibration isolation rate. The vibration isolator may be disposed within and assembly including at least a first part and a voltage source in electrical communication with the shape memory alloy. The product may further include a controller constructed and arranged to pass at least one predetermined current from the voltage source to the shape memory alloy such that the shape memory alloy enters a physical state that dampens vibration of the first part.

1. A product comprising:
a variable rate vibration isolator comprising a shape memory material having at least two physical states, wherein each physical state has a corresponding vibration isolation rate, disposed between an assembly comprising at least a first part and a stimulus source in communication with the shape memory material; and a controller constructed and arranged to pass at least one predetermined stimulus from the stimulus source to the shape memory material such that the shape memory material changes from a first physical state having a corresponding first vibration isolation rate to a second physical state having a corresponding second vibration isolation rate that dampens vibration of the first part.
