To a helicopter the shaking seat system can simulate the vibration caused by the main rotor, tail rotor, engine, weapon firing, landing, etc. This paper focuses on the research and analysis of the shaking system of a helicopter flight simulator. The vibration model of the seat is built and the system is also developed. According to different flight states of the helicopter the vibration states of the seat are classified based on real measurement data, and the spectra of the vibration are interpolated to model the vibration of the seat. An electro-hydraulic servo system is used to drive the seat to shake along the direction that is parallel to the vertical body axis. The seat is shaken under the instructions at reference height with position close-loop control method, and the control law is PID algorithm. Running parameters of the system are configured by the software. The motional states of the shaking seat are displayed to the user through the visualization software. The main parts of the system and some key technologies of the implementation are also presented in the paper. The system can generate the special vibration environment in the helicopter flight process, and is successfully applied to the flight simulator. So the pilots' immersion feelings are increased. |
