The whole transmission matrix method for coupled bending-torsional vibration analysis was introduced and the transmission matrix of gear-coupled unit by considering the bending-torsion coupling was derived. Let the whole transmission matrix method be spread and applied into the problems of kinetic calculation of bending-torsional vibration for multi-axle system of gear transmission rotor that includes the effect of gear engagement. By adopting the whole transmission method to carry out calculations on critical rotation speed of the mutually coupling system of multi-rotor that possesses gear engagement. The result of calculation shows that this is a kind of simple and practical method with high accuracy, and suitable for the application on microcomputers by engineers and technicians.
