Manipulate Mechanism Design and Synchronous Motion Simulation for Helicopter Driving Simulator

Abstract

A new manipulate mechanism with automatic position reset function for helicopter driving simulator is proposed and developed. The motion platform of the driving simulator and the synchronous motion analysis are designed. The synchronous simulation research is carried out. By using the simulation method, the availability of the mechanism and the feasibility of synchronous motion are verified. It provides a new design scheme and develops synchronous motion analysis method for the manipulate mechanism of the helicopter driving simulator. Firstly, the mechanisms and models of the manipulate stick and the driving simulator are established. The mathematical modeling and kinematic derivation are carried out respectively. Secondly, the dynamic simulation of the manipulate mechanism is carried out and the driving simulator model is built by using MATLAB/Simulink. In order to control the attitude adjustment of the helicopter driving simulator, the mapping relationship between the manipulate mechanism and the 6-DOFs platform is established. And the effect of synchronous motion simulation is achieved. The simulation results show that the manipulate mechanism can perform the load simulation of the joystick by spring compression and is feasible to control the driving simulator. Comparing with formerly electric load simulation, this research provides us a new way to achieve manipulate stick load simulation by mechanism design for helicopter driving simulator. The simulation result curves verify the proposed research method is reasonable and practice for helicopter driving simulation.
