| Abstract: | The mathematics model for the extra force of electrical liquid load emulating platform is deduced in detail. Many factors influencing extra force are analyzed theoretically. The influences of leakage coefficient of loading system total flow and the angle disposition of rudder on extra force are analyzed by means of elimination. According to the analyses, a scheme, which a connecting hole is added to the two loading cavities of loading motor and synchronal compensation, to eliminate extra force is made out. The effectiveness of this method for eliminating extra force is validated through experiment. |
