Active vibration dampers

Active vibration dampers

The Linz Center of Mechatronics GmbH offers cost-effective active vibration damping. The actuator reduces vibration automatically (Plug&Play) at the applied point by use of a built-in acceleration sensor and a robust adaptive control design.


DESIGN FEATURES

The active vibration damper is held in its zero position by a mechanical spring and deflected from this position electromagnetically. This design allows the actuator to be used in any position and cover a wide frequency range. The combination of permanent and electromagnets and the optimised ratios of the mechanical and electromagnetic factors make it possible to achieve high performance with small size and low weight.

A plug-and-play application is possible thanks to the built-in acceleration sensor and adaptive control algorithm. The algorithm minimises the vibrations at the location of application automatically and effectively.


VIBRATION DAMPERS – TECHNICAL DATA

  • Total weight: approx 800g*
  • Moving mass: approx 500g*
  • Output: approx 30W*
  • Magnetic force: 40N*
  • Max. dynamic force at 10 Hz (resonant): 150N*
  • Deflection: +/- 1mm*
  • Frequency range: 40Hz to 200Hz*

*) Example for specific size. The principle is scalable and feasible in any size.


BENEFITS
• Any mounting position
• High power density
• Feasible at any size (principle is scalable)
• Plug&Play
• Cost-effective total system

APPLICATIONS

Thanks to its robust and easy operation, the active electromagnetic vibration damper can be used in practically any situation where there is sufficient space for installation. Examples include:

  • Automotive (e.g. active chassis damping)
  • Engineering/Machine tools (e.g. reduction in vibrations transmitted into the foundation of a machine)
  • Construction
  • Medical technology
  • Robotics
  • Energy supply
  • etc
