摘要
PURPOSE: To provide the method for predicting nonlinear characteristics of the system including nonlinearity which enables a guide for reducing pressure pulsation, etc., generate in a hydraulic pressure system or mechanism system by predicting nonlinear characteristics that can be represented by a fragmentarily linear system. CONSTITUTION: In the system including the nonlinearity represented by the fragmentarily linear system, the fragmentarily linear system uses a nonlinear spring element whose nonlinear area and linear area can be represented through border points (a) and (b) in the relation between displacement and loads, displacement XI in time steps T and t which are fixed or varied at specific time is found in order by N-step repetition from 1 in time series, and the nonlinear characteristics of the system are predicted from the displacement Xi found in the time series.
