MATHEMATICAL MODELING BY THE DESIGN ENGINEER,
Abstract
The paper describes the type of model that is being developed for a hydraulic valve/actuator combination and discusses some fundamental characteristics of the dynamic operation of this type of hardware. Mathematical modeling presents the fluid power system design engineer with a simple and fairly accurate method for analytical simulations. A simulation of a hydraulic actuation system has resulted in performance which closely follows the performance of the actual hardware. A simplified version of this model was used to investigate the resonant-amplitude peak dispersion common to hydraulic systems. It was determined that this dispersion is primarily a function of the relative magnitudes between the cylinder and supply pressures. When the cylinder pressure is greater than the supply pressure, flow through the open valve ports is reversed thus lowering the cylinder pressure and reducing the resonant peak amplitude and frequency.
