The analytical development of A.P.T.-P transmission 4. Natural frequency examination (25 kV version) (IM-PS-133)

This memorandum represents a slight digression from the environmental vibrational studies of the earlier memoranda of this present series. An examination is made of the transmission's natural torsional and longitudinal frequencies, during both the coupled, non-slip mode and the decoupled, slip mode. The results which are presented are complementary to...
