    Abstract
  • In order to analyze the formation and influence factors of the extraneous torque of pneumatic load simulator, the working principle, structure diagram and experimental platform of the pneumatic load simulator were introduced and the mathematical model of the pneumatic load simulator was deduced. The model was verified through comparing the result of experiment and simulation. The three influence factors (passive pressure, moment of inertia and friction torque) of the extraneous torque of pneumatic load simulator were analyzed qualitatively by using linearization method. The influence of the three factors on the extraneous torque of pneumatic load simulator was analyzed quantitatively by using nonlinear simulation. The conclusion is that the friction torque is an important factor which comes into the extraneous torque in pneumatic servo loading system.
