High-Dynamics Hexapod as Motion Simulator

Testequipment with Six Motion Axes for Laboratory and Industrial Use

  • Direct magnetic drives for high accelerations
  • High motion repeatability in the submicrometer range
  • Operating frequencies of >100 Hz for small strokes
  • Running of predefined motion profiles

Dynamic Motion and Scanning in Six Axes

Motion simulators have higher motion dynamics requirements (shakers). They repeatedly perform defined motion cycles, for example for quality assurance and function monitoring of products in mobile use. Motions that are generated, for example, by trembling hands or a moving car, are simulated by means of sine curves and freely definable trajectories.

Six degrees of freedom allow fast motion sequences to be repeated identically in different locations of the workspace.

Applications

Testing of image stabilization algorithms in camera systems, also for mobile devices. In the process, the Camera & Imaging Products Association (CIPA) Standards must be taken into account.

Simulation of oscillations, e.g., eye motion simulation and eye tracking in the medical field.


Drive Principles

To generate highly dynamic motions, various drive principles can be used. Hexapods with electromagnetic, brushless torque motors and an appropriate mechanical design of the drive train and sensor system can already provide velocities of up to 25 mm/s and accelerations of up to 2 g.

The best dynamic performance is achieved by hexapods with magnetic PIMag® direct drives; they offer velocities of several hundred mm/s and accelerations of up to 4 g. The special design which includes flexure joints completely dispenses with rolling or frictional elements, thus allowing a zero-backlash motion without mechanical noise.
