| Abstract: | Based the transmission structure in the nacelle of tilt-rotor,the complex gears and shafts coupling dynamic modeling and dynamic response equations were built.And,three types of the force characteristics on the blades: cruise,hover and transition were analyzed.The dynamic response was computed using Runge-Kutta method to obtain the dynamic gearmesh coefficient.Finally,the natural frequency was discussed.The results provide some useful information to analyze the reliability and the dynamics optimization of the transmission. |

| Keywords: | tilt-rotor transmission response dynamic coefficient natural frequency |
