Three-beam constant-force flexure-based translation stage

Simon Nessim Henein, Florent Cosandier

Flexure-based constant-force mechanisms belong to the category of zero-stiffness mechanisms. They present a non-zero elastic restoring force which does not depend on the deformation of the mechanism. However, their design and modeling are frequently comple ...

Dynamic balancing of a flexure-based Watt's linkage horological oscillator

Simon Nessim Henein, Florent Cosandier, Hubert Pierre-Marie Benoît Schneegans

Mechanical watches are generally regulated by a balance and a spring constituting a harmonic oscillator. This mechanism is intrinsically force-balanced, which makes it essentially insensitive to gravity as well as to the linear accelerations of the watch. ...

Rectilinear Flexure-based Translation Stage Family with Minimized Parasitic Shift, High Support Stiffness and Large Range of Motion

Simon Nessim Henein, Florent Cosandier, Loïc Benoît Tissot-Daguette, Célestin Vallat

This article presents a novel family of exactly-rectilinear translation mechanisms, called the "QUADRISTAGE family", based on one-degree-of-freedom planar kinematics exclusively using pivot joints and rigid segments. Several variants are presented, some pr ...
