Abstract�� The helicopter rotor test-bed is one of the main equipments to test the helicopter rotors. The testing effect and control accuracy can be improved by making kinetics analysis and building the model of the helicopter rotor test-bed. The helicopter rotor test-bed structure and functions were introduced, and the pitch link loads was simplified. The dynamic model of the helicopter rotor test-bed was built by making the force analysis of the swash plate. According to the simulation of the hydraulic model and test-bed model, the dynamic response and interactive coupling influence were studied in the different gestures of the rotor system. The system responses were made in different load characteristics. The modeling and analysis of the test-bed can give a theoretical support on the control of rotor gesture and improvement of the excitation accuracy, and be helpful for the design of the test-bed and control system.
