The EX170 rotating body dynamics bench allows the experimental study of the balancing of a rotating assembly, the visualization of vibration phenomena and the validation of observations using the associated software VIBROTOR. p >
The EX170, EX180 and EX185 benches allow:
The EX170 test bench consists of a shaft, guided in rotation by two bearings and fitted with four plates. The assembly is elastically connected to the support by means of two pairs of steel blades. Weights, of various values, can be fixed on each of the plates to achieve the balancing or unbalancing of the rotating assembly. The spinning is done manually using a launcher.
The bench is identical to the EX170 bench, but two of the steel blades, supporting the rotating assembly, are equipped with strain gauges for measuring the displacement of the bearings and the forces. A magnetic angular proximity sensor allows the measurement of the position and the speed of rotation. The sensors are connected to the EI616 strain gauge bridge, itself connected to the acquisition card supplied, via the analog output of the bridge.
This bench takes all the characteristics of the previous benches, but it allows to study the balancing of bodies of any shape.
The two plates close to the bearings are fitted with flanges, on which self-adhesive balancing weights can be placed. In addition, one of the plates can be replaced by a solid holder, on which the bodies to be balanced will be placed.
