Estimating the term…
A displacement amplifier receives an actuation displacement signal from a piezoelectric actuator. The displacement signal is amplified by one or more stages of compliant elements, and a corresponding force is applied to a load. Wide frequency response is achieved in response to the resilience characteristics of the compliant elements that are formed from any of several materials, illustratively aluminum, steel, titanium, plastics, composites, etc., and are produced by any of several manufacturing techniques, illustratively extrusion, die casting, forging, etc. The compliant elements can be configured as plural compliant mechanical displacement amplifier stages. In bilateral arrangements displacement signals from distal ends of the motive source are applied to symmetrical, or mirror image, arrangements of compliant elements. The motive source, which may be a piezoelectric actuator, delivers its displacement signal at one end thereof to one or more compliant elements. The other end of the piezoelectric actuator can be grounded.
A motion transducer, comprising:
The motion transducer of claim 42, wherein there is further provided a second compliant transducer arrangement installed on said base member, said second compliant transducer arrangement having an input for receiving a second vibratory input displacement and an output for producing an output force directed at a further predetermined angle with respect to the longitudinal axis of said base member, said vibratory actuator element having a second output portion coupled to the input of said second compliant transducer arrangement for producing the second vibratory input displacement.
An energy absorption system comprising:
