Effect of Oil Flow Velocity on Hydraulic Shock

Abstract

The article is focused on experimental investigation of oil dynamics in long pipe at non-stationary flow. The non-stationary flow is realized by sudden closing of seat valve at the end of the long pipe. For this reason the oil pressure is suddenly increased and hydraulic shock is created. There is described the influence of oil flow velocity on hydraulic shock in this article. The pressure is measured near the seat valve. Furthermore this process is mathematically simulated using Matlab SimHydraulics software and is compared with the experiment.

An Analytical Model for The Capacitance of Stainless Steel Braided Reinforced Teflon Aviation Hoses

“…At present, SSBRTH assemblies are mainly used in various hydraulic, pneumatic and fuel systems in the aviation and aerospace fields where need high performance and quality [10]. Hydraulic system dynamic is significantly affected by oil bulk modulus, hydraulic hose elastic modulus and hose length [11][12][13][14]. The capacitance of hoses representing the change of the inner cavity volume under the unit pressure change is the key parameter to characterize the hose elasticity.…”
