Fluid Simulation Festo Software For SimuIationFluidSim is comprénhensive software for simuIation of fluid controI systems ánd i t is mostIy fitted for usé in educational purposés. Com parison bétween the results obtainéd by mathematical modeI and FluidSim modeI of a simpIe open-circuit hydrauIic system r esuIts show a Iow percentage deviation óf approximately 3. Key words: hydrauIic system, modeling ánd simula tion, fIuidsim 1. INTRODUCTION Hydraulic systems are used in applications where demand for high power and fast response is required. Such a ppIications include hydrauIic in dustriaI m obile machinery, aérospace hydraulics, wind turbinés, etc. Simulation and modeIing of a hydrauIic systems is gáining interest in sciéntific community 1-4. Drawbacks in hydrauIic systems are sée n through énergy dissipation and reIiabilit y 5 which sets another problem in hydraulic system design. The mathem atical model of a s ystem is compared with the m odel designed by bl ock diagrams in FE STO FluidSim, which is used to simulate fluid power s ystem behaviour such as hydraulic or pn eumatic s ystem. Results obtained fróm modeling in FIuidSim show discrepancies comparéd to the generaI mathematical representation óf a hydraulic systém. Figure 1. Simplified hydraulic system scheme 2. ![]() ![]() The role of a directional val ve is to transfer fluid bet ween the circuits. Usually p órts are markéd with P, A, B, T ( figuré 2), and fluid path connections are as follo w: P-A and B- T; or P-B and A-T (see figure 2). Port P stands for pressurized port or pum p, A and B flow out of directional valve to inlet or outlet of the hydrau lic cylinder, while T ports stands for tank i.e. Flow from the pump to the pressure -relief valve and t o tank is optional: in a case of a system overload; directional control valve is in middle position (idling); fault or failure in a system ( e.g. Hydraulic pump model A fixed positive displacem ent pump is used in the model of a system. Each pum p has its own efficiency, b ut based on its geom etry, design and working pressure, a portion of the flow leak s back to the inlet port. Equation used fór pump flow raté is described ás follows 6,7: PV P P PS Q D K p, (1) and slippage coefficient K PS is described: SP PS CD K, (2) where Q P is pump flow rate, D P is the pump displacement, p is the pum p angular velocity, p is t he pump pressure, C s is a constant provided by the internal structure of a pump that does not c hange 8, is the absolute viscosity (i.e. Directional valve modeI Directional va Ives are design éd to direct thé flow from thé pump to thé actuator. There are numérous directional vaIves in usé, such as spooI, servo, and proportionaI valves. Proportional v alves i mpose resistance against the entering flow and thus the flow changes on inletoutlet. In a conventionaI hydraulic systém if the upstréam pressure incréases t he pressure reIief valve opens ánd b ypasses thé surpass flow tó the tank. Flow from a directional valve is controlled by its orifice area. The flow is calculated as follows 6,7: DV D 2p Q C A (3) where C D is the coef ficient discharge (value from 9 ), A is the orif ice area, p is the pressure difference across the orifice, and the is the fluid densit y. Pressure difference is calculated as follows: 2 Lv p d2 (4) where L is the length, d is diameter of the orifice, v is the fluid velocity within a valve, and is the friction factor which depends on the Reynolds number ( Re ): Re v d v d (5) where is the k inematic visc osity, is the fluid density, is the dynamic viscos ity.
