Novel Linear Hydraulic Actuator

ASME/BATH 2015 Symposium on Fluid Power and Motion Control, 2015
In 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-Quadratic Optimal Actuator Location

IEEE Transactions on Automatic Control, 2011
In control of vibrations, diffusion and many other problems governed by partial differential equations, there is freedom in the choice of actuator location. The actuator location should be chosen to optimize performance objectives. In this paper, we consider linear quadratic performance.

MODAL ANALYSIS OF LINEAR ACTUATOR

Issues of radio electronics, 2018
The question of checking the linear drive for resistance to resonance in the structure of the precision positioning mechanism for space applications - hexapod, when it is taken to a near-earth orbit is considered. Calculation of the values of the natural frequencies of the structure is carried out by the finite element method using CAD. The application

DNA-Structured Linear Actuators

Volume 5A: 40th Mechanisms and Robotics Conference, 2016
This work presents a series of DNA-structured linear actuators that have high displacements and compact profiles. These actuators operate by twisting and untwisting a double helix that resembles a DNA molecule. Unlike most similarly-motivated twisted string actuators (TSAs), these DNA-structured actuators can have the ability to exert both push and ...

SMA Linear Actuators

2004
The unique properties of SMA microactuators appear to be very attractive for microrobotic applications. In the following, SMA linear actuators and related optical microswitches and microgrippers will be discussed. As for SMA microvalves, a dedicated technological approach is pursued for their realization, which is based on micromachining SMA plates or ...

A novel ultrasonic linear actuator

[Proceedings] 1990 IEEE 7th International Symposium on Applications of Ferroelectrics, 2002
An ultrasonic linear actuator operated by a combined wave of longitudinal vibration and flexural vibration excited by nonlinearly connected bars is described. A multilayered piezoelectric actuator was used at the actuator, and aluminum bars as the elastic body.
