Abstract

The dynamic characteristics of hydraulic system were commonly analyzed by the time domain response. The rise time and maximum overshoot are both significant specifications for presenting the dynamic chrematistics. A dynamic pressure generator, was called pressure square wave generator (PSWG), was used as an input source for exciting the response of hydraulic devices. The testing frequency and amplitude of PSWG was arbitrary and the testing range was employed between 16 and 300 Hz. The primary objective of this paper was investigating the volumetric effects on PSWG. The volume was the chamber of a hydraulic cylinder and changed by controlling the stroke in 50 mm incensement between 0 mm to 200 mm. Results show that the greater the chamber volume obtained the larger the rise time, smaller the maximum overshoot and the waveform tended to trapezoid-like shape.
