XCITE 1300 TORSIONAL SERIES
The Xcite 1300T Torsional Series of modal exciters provides pure torque input into structures for modal parameter estimation without the bending mode coupling effects present when linear excitation is applied through moment arms. These systems are used in structure borne noise tests of structures such as automotive and truck transmissions, prop shafts, axles, differentials, and torsional engine dampers.
Additional applications of the 1300T Torsional Series are found in power generation where steam turbine rotor torsional resonances and their modal coupling with blade bending frequencies can be easily identified because of the pure torque excitation.
