Modal Exciters Types 4827 and 4828 promises a force rating of 650 N (sine) and 1000 N (sine) each. This makes them pretty useful in a range of mechanical structures in SISO and SIMO test setups. Main applications include truck body-in-white, large engines, large automotive structures, aerospace structures, locomotives, large industrial turbines, heavy-duty pumps. It is possible to use the device for challenging and uncompromised excitation of both big and huge structures in MISO and MIMO test setups. These modal exciters can be bought as standalone units, in which you get appropriate trunnion, blower and connecting cable. The device can be bought as complete systems, especially types 3627 and 3628 and they contain centering unit, matching power amplifier and field power supply.
