 note = {A practical simulation study of the hydraulic servomechanism was made to facilitate synthesis of the output driving mechanisms of automatic flight control systems, flight simulators and other mechanisms. A general non-linear mathematical model of a hydraulic servomechanism with load was established, which was composed of a position control system. The general model was specified to particular loading conditions for practical uses, e.g. spring load, viscous load, etc. These models cleared the utility range, comparing the frequency response characteristics of calculations and experimental data. As a result, it was verified that the mathematical models could accurately describe the dynamic behavior of a hydraulic servomechanism, with any specified loading condition, up to 10Hz., 資料番号: NALTR0421000, レポート番号: NAL TR-421},
