Beschreibungen/Notizen

• In the French watt balance experiment, in order to have a single point of application of a weight and an electromagnetic force balancing this weight, a monolithic system of double gimbals with flexure pivots was made out of copper‐beryllium alloy. It also allows a rotation according to four coplanar axes which intersect in one point. The parameters of stiffness of the flexure pivots have been determined by the way of a simple dynamometric method. The study of the dynamic behavior in air of this device has shown a very good decoupling between each gimbal.
