Modeling and analysis of miniaturized magnetorheological valve for fluidic actuation
Fluidic actuation enables movement in a wide range of mechanical systems, from simple laboratory devices to more complex industrial machinery. Fluids are used to generate motion of mechanical pieces. The term "fluids" encompasses two types of technologies: ...
EPFL2023Damping of flexure blades based on bi-material additive manufacturing
Simon Nessim Henein, Florent Cosandier, Nicolas Blondiaux, Loïc Benoît Tissot-Daguette, Elias Sebastian Klauser, Florent Alexandre Boudoire, Nikola Kalentics, Lisa Salamin
Flexure-based mechanisms have become state-of-the-art solutions for the design of high-precision mechanisms, free from friction wear, backlash, and lubrication. These properties which are necessary for applications in ultraclean or harsh environments, neve ...
2023Robust tunable acoustic impedance control on electroacoustic resonators for aircraft noise reduction
Air traffic noise emissions are responsible for a significant part of the overall environmental noise, especially in the vicinity of airports. Exposure to environmental noise is known to negatively impact health and to be associated with cardiovascular dis ...
EPFL2023Highly Efficient Miniaturized Magnetorheological Valves Using Electropermanent Magnets
Yves Perriard, Christian Köchli, Adrien Jean-Michel Thabuis, Sofia Lydia Ntella, Kenny Jeanmonod, Bhawnath Tiwari
Fluidic systems enable actuation in various applications, such as automotive, medical, and industrial robotics. Miniaturized valves constitute a fundamental controlling element of modern fluidic systems, intriguing the interest of many researchers. This le ...
2023SOFT BIDIRECTIONAL BENDING ACTUATOR BASED ON MAGNETORHOGICAL FLUIDS
The goal of this project is to design and fabricate a bidirectional bending actuator for soft robotics applications. The actuation principle will be based on magnetorheological fluids (MRFs). MRFs are smart materials consisting of micro-meter-sized particl ...
2023Seismic Design and Behavior of Steel Braced Frame Buildings with Friction Dampers as Dissipative Floor Connectors
Field observations and comprehensive life-cycle building assessment suggest that buildings designed according to today's seismic standards meet the life-safety requirement. However, they are prone to economic losses due to repairs in the aftermath of earth ...
EPFL2022Sound Field Reconstruction in a room through Sparse Recovery and its application in Room Modal Equalization
The acoustics of a room often refer to the quality of the room in terms of sound recording as well as sound reproduction. At low frequencies, where the wavelengths are of the same order of magnitude with the dimensions of the room, due to the standing wav ...
EPFL2021Unstable tilting motion of flexibly supported gas bearing bushings
Jürg Alexander Schiffmann, Philipp Kaspar Bättig
This paper presents measurements of the motion amplitudes from flexibly supported Herringbone Grooved Journal Bearing bushings. Measurements taken in four locations on the flexibly supported bearing bushing enable the distinction between the radial and the ...
2021Optical rotating torque sensor with nano newton-meter resolution based on a hanging torsion wire
Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann, Billy Nussbaumer
This article presents a novel torque measuring setup working in the nano newton-meter range. The central novelty is a long (1 meter range) thin (diameter of a few tens of micrometers) metallic wire used instead of the relatively stiff torsion zone of the s ...
2021Flexible Support for Gas-Lubricated Bearing Bushings
Herringbone-grooved journal bearings (HGJBs) for high-speed turbo-machinery are often supported on O-rings due to their favorable stiffness and damping characteristics for stability and alignment reasons. They yield limited lifetime at high temperatures, i ...
