Novel Linear Hydraulic Actuator
ASME/BATH 2015 Symposium on Fluid Power and Motion Control, 2015In the area of linear motion, infinite stroke only is provided by electric actuators today, until now there has been no hydraulic alternative. The novel linear hydraulic actuator consists of two double acting cylinders with a common piston rod. The working principle of this actuator for short movements is that at least one piston is connected to the ...

Linear ultrasonic piezoelectric actuator
Conference Record of the IEEE Industry Applications Society Annual Meeting, 1991A prototype of the linear ultrasonic piezoelectric actuator (LUPA) with a traveling wave was constructed, and fundamental characteristics were measured. In the prototype, the traveling wave was synthesized by supplying two-phase high-frequency electricity to the piezoelectric elements attached to the copper bar.

Cryogenic submicron linear actuator
SPIE Proceedings, 2010The Cryogenic Submicron Linear Actuator (CSA) is a medium range (±5 mm) submicron resolution linear actuator suitable to be used at cryogenic temperature (12K). The unit has been developed for fine positioning use. The unit is based on classic motor-gear concept with nut and screw; different materials and lubrications have been tested for the same ...

A flexure-based electromagnetic linear actuator
Nanotechnology, 2008This paper introduces a novel nano-positioning actuator with large displacement and driving force, termed a flexure-based electromagnetic linear actuator (FELA). It mainly comprises an electromagnetic driving scheme and flexure-supporting bearings that provide infinite positioning resolution and highly repeatable motion.

Linear Multimodal Actuation Through Discrete Coupling
IEEE/ASME Transactions on Mechatronics, 2014Due to technological limitations, robot actuators are often designed for specific tasks with narrow performance goals, whereas a wide range of behaviors is necessary for autonomous robots in uncertain complex environments. In an effort to increase the versatility of actuators, we introduce a new concept of multimodal actuation (MMA) that employs ...
