  • Publication number: 20140306576
    Abstract: 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.

  • Patent number: 8827250
    Abstract: A vibration reduction device includes: a rod rigid body supported between an engine and a vehicle body via respective elastic bodies, a resonance frequency of which is set to be lower than an engine rigid body resonance frequency; an elastic component that is provided on the rod rigid body and caused to deform by a force acting in an axial direction of the rod rigid body; an inertial mass supported by the elastic component; and an actuator that causes the inertial mass to reciprocate in the axial direction of the rod rigid body by generating a force that is proportionate to an axial direction velocity of the rod rigid body. As a result, resonance itself can be suppressed without reducing a double vibration proofing effect.
