Abstract:In order to obtain characteristics of torsional vibration for a transmission system of tilt-rotor driven by twin engines, its torsional vibration is calculated and analyzed. Based on a simplified structural of a transmission system of tilt-rotor, the transmission system is divided into the subsystems of shaft segment and disks. The torsional dynamic equations are build by the theorem of moment of momentum and the superposition principle of mode of vibration. According to the boundary conditions, the torsional dynamic equations of subsystems are combined into a torsional dynamic equation of the transmission system. After soluting the torsional dynamic equation, the torsional angular displacement of torsional vibration for a transmission system of tilt-rotor driven by twin engines is derived by the superposition principle of mode of vibration. A computational example is given. Torsional frequency response function of the transmission system are analyzed.
