1300T 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.
