The three available benches all have the EX170 base machine and the VIBROTOR software in common. The benches are upgradeable and it is possible to modify the initial EX170 configuration to transform it into an EX180 and EX185 configuration.



Technical specifications :

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.

The EX170, EX180 and EX185 benches allow:

  • Static and dynamic balancing of the rotating assembly without additional mass.
  • The study of the rotating assembly loaded by one or more masses.
    & nbsp;
  • Dynamic balancing of the rotating assembly loaded by a mass placed on a plate by adding one or more masses on the same plate or by adding masses on other plates.
  • The quantitative study of several types of vibrations: symmetrical, asymmetrical, damped vibrations (EX180 - EX185)
  • The quantitative study of several types of unbalance: unbalance force, unbalance torque, unbalance of any kind. (EX180 - EX185)
  • The rebalancing of the rotating system. (EX180 - EX185)
  • realization of static and dynamic balances of unbalanced assemblies by plates of any shape, as well as the measurement of the forces at the bearing (EX185)
  • The aim of the VIBROTOR simulation software is to illustrate the behavior of the rotating assembly and to determine how it can be rebalanced using point masses.

EX170
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.

EX180
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.

EX185
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.
