Product Profile: Physik Instrumente Motion Simulators
What is it? Motion simulators (shakers) reproduce movements of test objects and the simulators have high motion dynamics requirements. For example, they may repeatedly perform defined motion cycles for quality assurance and function monitoring of products in mobile use. This includes a range of motions of different magnitudes that are generated, for example, by a moving car or trembling hands. The simulator reproduces these movements using sine curves and freely definable trajectories. To generate highly dynamic motions, hexapods with electromagnetic, brushless torque motors and an appropriate mechanical design of the drivetrain and sensor system can provide velocities of up to 25 mm/sec and accelerations of up to 2g.
Applications include testing of image stabilization algorithms in camera systems and mobile devices, as well as eye motion simulation and eye tracking in the medical field. Camera & Imaging Products Association (CIPA) Standards are taken into account. 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 4g. The design includes flexure joints that dispense with rolling or frictional elements, thus allowing a zero-backlash motion without mechanical noise.
