F-1338 Simulation Dynamic Characteristic of Water Hydraulic System by OHC-Sim

Abstract

The development of the water hydraulic drive system is expected to solve the environmental problem. This paper deals with the dynamic characteristics of the water hydraulic drive system using tap water as a operating liquid, whose research and development is required from the view point of the environmental assessment and resources saving. The system using in the experiment is similar to a typical oil-hydraulic circuit consisting of a vortex pump, a relief valve, an electro-magnetic type on-off valve and a single rod cylinder. The step responses of pressure, piston displacement and load force in the operation condition of a low pressure as a tap water are obtained. And the dynamic characteristic was analyzed by a simulation program "OHC-Sim"
