Study on the Effect of Cracks in Diaphragm Couplings on the Dynamic Characteristics of Shaft System

Machines
Diaphragm couplings are prone to developing diaphragm cracks under prolonged high-speed operating conditions, which can lead to degradation in the performance of the transmission system and affect the dynamics of the shafting system.
