Ultra-high vacuum (piezo actuators
in versions specially designed for ultra-high vacuum)
Fabricating the IPMC actuator
with a preshaped form is possible via a simple thermal treatment process.
Basic dynamic equation of the piezoelectric actuator
are derived from the principle of minimum potential energy by means of variational functionals and can be written as follows [9-11]
is able to perform a25 mm maximum stroke, developing a 7 N force.
The rugged, versatile and fully configurable LX Actuators
are used extensively across a wide range of motion control functions in machine building, factory automation and assembly operations, packaging lines, QC testing and inspection.
These stand alone actuators
can replace electromechanical ball-screw actuators
in many applications, such as precise modulation of flue dampeners in thermal energy applications, modulated control of large gate and globe valves, slide gates for bulk materials handling, and raising and lowering security barriers.
In addition to being fully rebuilt, the actuators
will be modified to correct a problem identified during previous shuttle maintenance work, NASA officials said.
Suh have fabricated ciliary arrays in which each microscopic actuator
looks like the tail of a fish, curling upward from the surface.
The important new technology of wireless sensor and actuator
networks provides radically new communication and networking paradigms with many new applications.
Traveling wave piezoelectric actuator
which type is rotary is studied numerically and experimentally in this paper.
Key words: simulation, actuator
, artificial muscles
Removing the main-landing-gear retract actuators
should be an easy process for an experienced Prowler airframer: remove two bolts and two hydraulic lines, and the actuator
is in your hands, ready to go.
