Dynamics Response of Rotor- Supporter Flexible System with Variable Kinematic Structure

摘要

Taking the large sized spinning rocket-launcher system as example, this paper presents a hybrid aprpoach to model the dynamic characteristics of roto-connection-supporter flexible system with variable kinematic structure. The coupled vibration behavior between the rocket and supporter is analyzed. A numeral solution is developed for the system transietn response while the constrained conditions are changed suddenly. The influence of the bending flexibility and spin rate on dynamic characteristics of the systme are discussed, and some important conclusions are obtained.
