Talk about how the diaphragm coupling handles resonance

　　The diaphragm coupling will be subjected to the operation caused by the vibration of the transmission system during the operation process.When these outside worlds are close to the natural frequency of the coupling system, resonance will occur.In order to prevent the coupling from resonating, it is necessary to conduct modal analysis of the coupling to determine the natural frequency of the structure, so as to provide basis for the analysis of the system's oscillation characteristics, the diagnosis and forecast of oscillation faults, and the optimal planning of the dynamic characteristics of the structure.

　　In modal analysis, only useful bindings and loads are zero-displacement bindings. Other loads can be specified in modal analysis, but they will be ignored during modal extraction.Considering that the coupling rotates around the central axis, a full-degree-of-freedom binding is applied to both ends of the coupling finite element model.Since the lower natural frequencies of the coupling system have a great influence on its dynamic care, only the first few natural frequencies need to be understood in the study and analysis.The diaphragm coupling is used to connect the engine and the reducer. When the excitation frequency caused by the engine is combined with the natural frequency of the coupling, it will constitute the occurrence of resonance.
