At least 6 vibration shakers are located in 3D space with integrated control and can create 6 DOF motions (3 translation DOF and 3 rotating degrees). In addition to X, Y, and Z axis motion, rotational motion, Roll, Pitch, and Yaw are also possible utilizing spherical bearings. Using electrodynamic vibration generators, IMV systems can reproduce waveforms that have components in a wide frequency range with a high degree of accuracy. System maintenance is easy. Systems comprise at least six vibration generators to act along orthogonal axes and also to generate the roll, pitch, and yaw components of vibration. A spherical bearing is used to allow rotational motion. By using electrodynamic vibration generators the system can operate over a wide frequency range with a high degree of accuracy. System maintenance is straightforward.
Features
Ride comfort evaluation system
The addition of rotational motion to a three-axis system enables 6 degree-of freedom testing, as is required for vehicle seat evaluation, for example.
