TTS-series
(6 Degrees of Freedom Systems)
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.
Simultaneous Three-Axis (MA-Series) Shakers 10 - 60 kN (2200 - 13,200 lbf)
Real-world vibration happens in all directions and thus it is necessary to test the DUT in all three directions simultaneously. The MA Series of three-axis shakers is designed and manufactured for this vibration testing purpose. Key Applications: •Testing in accordance with MIL-STD-810G Method 527 requirements •Testing in accordance with IEEE-344 multi-axis vibration testing •Vibration qualification testing for aerospace/military components and systems •Automotive NVH/BSR and component testing Features/Advantages •Simulates real-world vibration requirements •Reveals different DUT response dynamics under simultaneous multi-axis excitation than possible during single-axis vibration testing •Identifies failures which could not happen with single-axis vibration testing •Reduces testing time by two-thirds for significant cost savings over single-axis vibration testing in each axis •Can be integrated with Sentek Dynamics’ THV Series environmental test chambers Multiple-Input Multiple-Output (MIMO) Control Sentek Dynamics’ MA Series simultaneous 3-axis systems use the Crystal Instruments’ Spider System vibration controller for advanced MIMO vibration test control. The Spider System recreates multiple degree-of-freedom vibration environments in the testing laboratory and provides all required control types including MIMO Random, MIMO Sine, MIMO TWR, and more. For more information regarding the Spider System see the Vibration Controllers section or contact the Sentek Dynamics’ sales office.
Environmental Test Systems
These products are primarily used to test manufactured products by exposing them to thermal and mechanical stresses. IMV can supply vibration test systems combined with climatic chambers to enable complete vibration, temperature, and humidity environmental testing. These systems can be custom-designed to fit your specific application.
