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.
Drive Principles
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.
