Requirements concerning installation and power supply of shakers
Depending on the type of the shaker system, it is necessary to observe the following recommendations concerning installation of the shaker system:
- low-capacity shakers intended for calibration and verification of the transducers (for instance, TV 50018) can be placed on decks and drawer units for the convenience of the operator. However, it is still recommended to use task-specific furniture with thick benchtop, or to install the shaker on supporting pins, so that to avoid occurrence of a strong resonance. Shakers of this type normally have rubber supporting pins;
- medium-capacity shakers should be placed on floor or foundations;
- high-capacity shakers can be placed on the floor only. Large shakers may have pneumatic relief units intended for compensation of shaker oscillations, which are in phase opposition to the oscillation of the specimen under test. In the case of large shakers, that are not equipped with pneumatic relief units, it is recommended to use foundation with vibration insulation properties.
The best foundation option for the shakers is a solid-cast concrete cube (shaker’s trunnion is attached to it with bolts). In office or laboratory environments, the shaker with rubber supporting pins can be placed on the floor. However, it is not convenient to operate a shaker placed on the floor, so another recommended option of shaker installation is to place it on a separate drawer unit without shelves (the thicker the panels are, the better). The stiffening rib of the upper surface should have central position.
Below you can find several types of electrodynamic shakers and the relevant recommendations for their installation and power supply:
