“…Fortunately, because of their large forcing capabilities, it is possible to employ various amplification techniques that sacrifice some of this forcing potential to amplify the actuator's stroke. Several researchers have been successful in employing external leveraging mechanisms coupled with piezoelectric stacks to amplify actuator displacement 1,2,3 for a variety of applications such as heavy machinery isolation mounts 4,5 , active rotor blade flaps 6,7,8 , and fuel injectors 9 . While these externally amplified actuators posses a high power efficiency for a given actuator mass, the additional components necessary for this amplification greatly reduce the actuator's volumetric power efficiency.…”

The piezoelectric telescopic actuation architecture capitalizes upon an internally leveraged amplification technique to produce large actuation forces with amplified displacements. This building-block type actuator consists of interconnected concentric, cascaded cylinders with end cap joints that allow for a telescopic type motion. The internal amplification scheme and building-block nature of the telescopic design allow for efficient, densely packed actuators that yield a high work output for a given volume. This paper presents an experimental investigation of the quasi-static force-deflection performance of three unique telescopic prototypes, each manufactured by different means, from various materials, and in distinct geometries. To accurately predict the observed behavior of this architecture, a full three-dimensional numerical model was constructed for each prototype and was used to revise a previously derived analytical model. These models were refined to include extra compliance factors to account for observed actuation losses, focusing primarily on the bonding layer effects. The revised models captured more accurately the complex actuator behavior observed in the experiments and characterized better the loss mechanisms in the telescopic actuation architecture.

“…Examples include the Moonie 20 , Cymbal 21 , X-frame 22 and double X-frame 23 . These actuators are employed primarily in high force applications such as proof mass actuation 24 , micropositioning 25,26 , and active/passive vibration control 27 , particularly in helicopter rotor blades [28][29][30][31][32][33][34][35] , suspension control 36 and vibration damping in machine tools 37 .…”

Actuation development and evaluation for INSTAR: inertially stabilized rifle

In the use of piezoelectric actuators, it is a clear choice to use stack (or d 33 mode) architectures when very high force is required or bender (or d 31 mode) architectures when very high displacements are needed. However, the choice isn't as clear for applications that need simultaneously moderate to high force and displacement. This paper presents one such application, INSTAR, which is posed with this dilemma. INSTAR is a novel rifle system that has an inertially stabilized barrel via an active suspension based on piezoelectric actuation. While the frequency required for this application was low (~10Hz), the displacement (± 200 to 400 microns) and the force (22-45 N) are moderate. Two very different actuation approaches were developed, modeled, fabricated and experimentally validated within the INSTAR demonstration platform: 1) a d 31 approach based on the Recurve architecture with focus on generating higher forces than is common for d 31 actuators and 2) a d 33 approach based upon a compliant mechanism designed using topology optimization with focus on providing more amplified strain than is common for d 33 actuators. Both approaches were successful in meeting the INSTAR requirements, but each had its own advantages and disadvantages.
