6 or more vibration shakers are located in 3D space with integrated control and can create 6 DOF motion (3 translation DOF and 3 rotating degrees). They can create motion along the X, Y, and Z axes, as well as generate roll, pitch, and yaw movements using spherical bearings. These systems are easy to maintain and comprise at least six vibration generators to create motion along orthogonal axes and rotational movement. The system can operate over a wide frequency range with a high degree of accuracy.
