VIBRA-9001
Manufactured by Life Testing Machines
The VIBRA-9001 is the first mechanical vibrodyne with linear actuator. This specialised piece of testing and diagnostic equipment is indispensable in all dynamic identification activities with EMA (Experimental Modal Analysis) techniques and in all cases where it is necessary an appropriate and constant forcing, even at low excitation frequencies.
Its structure is made entirely of lightweight aluminum. This makes it particularly manageable and easy to transport at the structure to be investigated, without the help of machinery lifting and handling equipment, reducing time and installation costs.
Using the RTC 9000-VIBRA Real Time Controller and the SHAKER software tool (see Models & Accessories tab), it’s possible to set the oscillating frequency (in steps or in frequency sweep mode) and the dwell time at desired frequencies.

Benefits
- Available in different sizes according to applications (customisable to specific needs).
- Modular masses are set in motion by the linear motor and can be easily placed on the upper tray, allowing the generation of different forcing according to requirements.
- Optimised for portability.
- Completely oil-free mechanics with low power consumption.
- Control system automatically and continuously manages the distance travelled by the slide to keep the forcing value constant along with the frequency variation.
- Special fixing plates allow a simple and effective anchoring of the vibrodyne to the structure to be investigated.
- Supplied complete with a laptop for use on site.
The VIBRA-9001 is designed for applications in civil engineering field, able of generating constant amplitude forcing along with the frequency variation. This makes it a vital tool for a wide range of structural analysis and research activities. Examples of applications can be seen in the videos below.
