Shakers for Stinger Excitation and Direct Clamping Capability
Dual-purpose electrodynamic shakers from The Modal Shop (PCB Piezotronics, Inc.) can be used for structural excitation in modal analysis, with the added capability of mounting test specimens weighing up to 4.5 kg directly on the 80 mm diameter armature plate and subjecting them to sustained vibration testing. The test frequency can be up to 6,500 Hz in both operating modes, with a maximum stroke of 25 mm. The Model 2075E can excite structures up to 334 N and has a through hole with chuck to accept the stinger with adjustability of the stinger length used. A stronger shaker is also available with the model 2100E.
