Electromechanically actuating molecules

2015 Fourth Berkeley Symposium on Energy Efficient Electronic Systems (E3S), 2015
Controlled motion at the nanoscale is an emerging avenue for low powered electronics. The necessity for precision at the nanoscale makes organic chemistry an exciting addition to electronics, as organic synthesis is based upon the design and creation of nanoscale and sub-nanoscale structures.

The "cymbal" electromechanical actuator

ISAF '96. Proceedings of the Tenth IEEE International Symposium on Applications of Ferroelectrics, 2002
A new transducer design was developed named the "Cymbal Transducer" with larger displacement, larger generative forces and more cost effective manufacturing. The cymbal transducers consist of a cylindrical ceramic element sandwiched between two truncated conical metal endcaps, and can be used as both sensors and actuators.

Camber Actuation of an Articulated Wing with Electromechanical Actuators

2021
This paper relates the design of electromechanical actuators for camber actuation in a morphing flap. In order to reduce fuel consumption, the camber of an articulated wing or flap is controled to reach specific aerodynamic profiles. The wing is divided in 6 parts, connected with 5 hinges. The angles of the hinges are controled by the electromechanical

Damping for electromechanical actuators

The Journal of the Acoustical Society of America, 2007
Oscillation and other disturbance damping is provided for a system having a load driven by an electric motor. Damping is achieved using feedback in an active mode, where power is supplied in a normal operation mode of the electromagnetic actuator. A gear train or other mechanical advantage device is connected between the electromagnetic actuator output

Dynamic modeling of an electromechanically-actuated launcher

2016 17th International Carpathian Control Conference (ICCC), 2016
In ground-to-ground military engagements, launchers used in land vehicles play an important role for armies. In application, orienting missiles and rockets which are fired from the land vehicles and finally hitting the intended targets with high accuracy are issues that should be taken into consideration.

Electromechanical Actuation Development

1978
Abstract : Electromechanical actuation of primary flight control surfaces has been demonstrated by the development of an integrated rotary hinge-line dual- redundant actuation unit. The characteristics of the developed hardware closely correlate with the design predictions.

Control of an electromechanical camless valve actuator

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2003
This paper addresses the modeling analysis and soft seating control of an electromagnetic actuator used in electromechanical camless valve-trains. Our mathematical modeling analysis reveals the instability of the actuator dynamics linearized around the seating position and zero velocity.
