A novel compression type coupling which can transmit large torque and high speed is studied.By using finite element analysis software ABAQUS
the dynamic torsional stiffness is analyzed
and the dynamic stiffness characteristic on the different torque is discussed.The result shows that the gear-type rubber coupling dynamic torsional stiffness is related to the torque
it increases with the increase of torque and it decrease first and then increase with the increase of frequency.It can provide the guiding significance for high frequency vibration isolation.
