She only had two shafts and two turbines, unlike the four shaft arrangement of the other ships of her class.
The presented results, which verified the applicability of this method, were obtained for three filter channel systems and six filter shaft systems.
Since six masses are considered in the shaft system, there are six modes of oscillation, named from Mode 0 to Mode 5.
The proposed dynamic balance method was validated experimentally using a shaft system with four rotors and five bearings which rotating up to 2700 rpm.
Stability of parametrically excited torsional vibrations of a shaft system composed of two torsionally elastic shafts interconnected through a Hooke׳s joint is studied.
When the mechanical damping is assumed to be zero, the motion equations of the shaft system are as follows.
The shaft system of GEN 1 comprises six torsional masses.
The two components are essentially linked by elastic shaft systems and may also embrace gearboxes and elastic couplings.
By December, only two of the three shafts were operational and a complete overhaul of the propulsion system was required.
The secondary battery of 6-inch (152 mm) guns and the three-shaft system were influenced by German design practices, while the engine and boiler layout was reminiscent of the Italian battleship.
