Abstract

The multi-shaft transfer matrix method(TMM) with differential gear mesh and the torsional vibration characteristics of the helicopter power system have been investigated.Firstly

the analytical model for the helicopter power system was built by the transfer matrix method.Next

the 'mesh transfer matrix' for the two-shaft and three-shaft gear pair

and the planetary gear pair were established using transfer matrix method.Then the torsional vibration characteristics of the helicopter power transmission system were obtained using the multi-shaft transfer matrix method.Lastly

the natural frequency and vibration mode properties was discussed
