Force cancellation demonstrator - Internal project

A rebuild of the Bosch Rexroth demonstrator was made with the addition of force cancellation, developed to optimize machine performance.

A gantry stage fair demonstrator was developed in cooperation with Bosch Rexroth, see Bosch Gantry demonstrator. MI-Partners has rebuild this stage with a force cancellation add-on. This force cancellation is enclosed in the specially developed AVI-mount active suspension.  The forces exerted by the acceleration of the stage are compensated by an active force generated inside these mounts.

Challenges
  • Creating a competitive suspension platform with a 6 DOF force cancellation functionality in a compact build-in volume
Key Competences
  • System design
  • Dynamics and vibration control
  • Mechanical design (for stiffness and DOF)
  • Control
Results
  • Vibration isolation system with unique high modal damping of >20% at 5Hz
  • Ability to accelerate stage up to 9.5 m/s² without visible movements of the granite base
  • Use of commercial actuators resulting in a cost-efficient design
  • Smart mechanical decoupling of actuation directions resulting in easy build-in of AVI-mount in existing platforms
  • Patented design
Cooperation
  • Bosch Rexroth
  • VHE
