Design of Electromechanical Motion System for an Aircraft Flight Simulator

Aircraft flight simulators with motion systems play a major role in improving education quality, flight safety and reducing training costs. Stewart mechanism is one of the simulator motion systems, which is a six-degree of freedom mechanism with coupled structures which makes its dynamical control analysis become more complicated. In this research, an electro-mechanical motion mechanism with six degrees of freedom has been completely analyzed and designed. With respect to the translational and rotational velocity and acceleration, and weight of cabin complex, kinematic relations of the machine, motions in work space with moving platform have been analyzed to calculate the positions, velocity and acceleration at any moments. The effects of various parameters such as roll, yaw, pitch, the linear and angular velocity and acceleration of the top platform on the force and speed of the operators are numerically studied finally. its components, namely electro-motor power, the length and diameter of ball screw, legs lenghth, lower platform, and leg linkage variations are, were analyzed and designed.
