Distributed parameters model of electromechanical actuator

Proceedings of the Fifth International Workshop on Robot Motion and Control, 2005. RoMoCo '05., 2005
In this paper is considered modelling of voltage forced electromechanical actuator taking friction and spring stiffness into account. 3D distributed parameters model including eddy current phenomena and magnetic non-linearity is presented. In numerical example a motion of movable armature is presented.

Electromechanical microswitches with thermal actuation

2002 International Microprocesses and Nanotechnology Conference, 2002. Digest of Papers., 2002
Conventional, semiconductor based electronics has its limitations in harsh environments, e.g. operation at low or high temperatures. micro- or nanomechanical switching elements may be an alternative to be used in logic circuits provided that they can be made small and fast enough for useful data processing.

Mechanism of electromechanical actuation in polypyrrole

Synthetic Metals, 1995
Conductive polymers, such as polypyrrole (PPy), undergo unusual mechanical responses when subjected to applied electrical potentials. This study reports on investigations into the molecular mechanisms of such responses in PPy, with specific reference to the role of the counterion and electrolyte cation.

Ferroelectric perovskites for electromechanical actuation

Acta Materialia, 2003
There has been a recent surge of activity in ferroelectric materials motivated by the desire for materials capable of large strains for actuator applications. New materials have been developed and systematic attempts to exploit underlying domains have been pursued.

Electromechanical Flight Control Actuation

SAE Technical Paper Series, 1977
<div class="htmlview paragraph">The new rare-earth sammarium-cobalt magnets are revolutionizing electromechanical actuation design to the extent that power-by-wire can be a legitimate follow-on to fly-by-wire. These new magnets coupled with innovative design techniques which feature direct interface with fly-by-wire are creating electromechanical

Ferroelectric actuators in the electromechanical interface

Optical Engineering, 1990
The function of a control system is to convert an operator cornmand into an electrical signal, to convert the electrical signal into a mechanical response, and to verify that the mechanical response achieves and maintains the desired level. A vital element in this interface is the electromechanical actuator.

Electromechanical Actuation for Business Aircraft

SAE Technical Paper Series, 1979
<div class="htmlview paragraph">The actual development and test of electromechanical actuation hardware for critical, manned aircraft, flight control application that is specifically designed to interface with fly-by-wire commands is now represented by only two hardware units. One of these units was built by Delco Electronics for NASA-Houston and

The design optimization of the electromechanical actuator

Structural and Multidisciplinary Optimization, 2008
This paper describes the design optimization of a flat-faced disk type of an electromagnet. In order to minimize volume and power dissipation, expressions for consumed power, magnetic attraction force, coil temperature and magnet volume have been obtained, depending on the dimensions.
