The Frequency Response of a Loaded Hydraulic Servomechanism

抄録

The first part of this paper, the frequency response of a loaded hydraulic servomechanism is calculated using an approximated method like the describing function. Next, a new method is introduced, namely input function is calculated which was a sinusoidal output with a settled amplitude. In this case the input function becomes an approximate sinusoidal function under certain restrictions. Handling frequency characteristics by this new method, calculation of nonlinear system becomes easier than by the first method. A few formulae developed in the paper lose the exactness in some cases of numerical calculation. The author also developed another formula which gave good result for such cases.
