Abstract:

The new air dynamical load simulator is that a position synchronous system is appended to a traditional load simulator to compensate for the position disturbance of the steering engine. Because between the synchronous motor and the loading motor, between the steering motor and the loading motor, there inevitably exist mechanical juncture links, the experimental conclusion is that even if the synchronous motor keeps synchronizing at position with the steering motor completely, the relative speed of the axis and shell of the loading motor can not be zero and disturbance torque can not be eliminated hundred percent.

Key words: load simulator, disturbance torque, stiffness
