6 dof shaking tables

Apr 16, 2021

The Multi-Axis Shaking Table (MAST) are designed for vibration testing of a wide range of test specimens. Vibration input can be generated in up to 6 degrees of freedom (6-DOF), either individually or simultaneously. MAST-Systems can be used for a variety of durability, performance and squeak and rattle applications
