Firstly, we establish “pilot seat” model in the biomechanical simulation software Anybody according to the physiological data of pilot and choose two main indexes: the muscle activity and joint torque. We change the seat height and the back angle respectively and the simulation data are obtained after the treatment of double variable 3-D surface chart. We analyze the influence of seat height and back angle changes by the major muscle activity and joint torque of the pilot. The mean value, variance and the square of the muscle activity are selected to evaluate the sitting comfort, providing the guidance for the overall layout of the cockpit and the geometric parameters design for the seat.
