Abstract

In order to meet the dynamic design requirements of helicopter supercritical tail transmission shafting, studied the self-excited vibration of floating spline-flexible shafting. According to the floating spline connection structure, established the spline tooth surface contact model and the positioning surface contact model respectively. With reference to the horizontal transmission shafting structure of a helicopter tail, a dynamic model of multi-interface floating spline-flexible shafting with floating splines, diaphragm couplings and rotating shaft was established. The effects of friction coefficient, external damping, unbalance and rotational speed on the self-excited vibration of the system were discussed. The results show that with the increase of the friction coefficient of the spline pair, the vibration response of the rotating shaft and the spline increases gradually; when the external damping and the friction of the spline pair meet certain conditions, the system may have self-excited vibration; when the self-excited vibration occurs, the system is in supercritical speed, and its vibration frequency characteristic is dominated by the 1-order bending frequency of the rotating shaft, and the closer the speed is to the 1-order critical speed, the higher the amplitude of the rotating shaft vibration response.
