HydFluid01A program that simulate fluid properties. The properties of the used hydraulic

fluid is calculated, interactively, based on the changes in working temperature and

pressure. The model generates, interactively, global fluid properties to be used

within the rest of the model.

HydConductor01A program that simulate a hydraulic conductor. The model calculates,

interactively, the differential pressure across a piece of conductor based on the

frictional resistance and moving fluid inertial effect. Line capacitance is used to

calculate flow out of the line based on the bulk modulus of the fluid.

4

HydOrifice01A program that simulate a hydraulic sharp edged orifice. The model calculates,

interactively, the differential pressure across the orifice based on the inlet flow

and a given orifice diameter.

5

HydFitting01A program that simulate a hydraulic piece of fitting. The model calculates,

interactively, the differential pressure across the fitting based on the inlet flow and

reported test data.

6

PumpModel01A program that simulate a hydraulic pump. The model calculates, interactively,

the shown output data based on concept of a 100% efficient pump.

7

PumpModel02A program that simulate a hydraulic pump. The model calculates, interactively,

the shown output data based on concept of a pump that works constantly under

same working conditions and has constant efficiencies . Given data are efficiency

curves.

8

PumpModel03A program that simulate a hydraulic pump. The model calculates, interactively,

the shown output data based on concept of a pump that works constantly under

same working conditions and has constant efficiencies. Given data are test curves.

9

MotorModel01A program that simulate a fixed displacement bidirectional motor. The model

calculates, interactively, the static characteristics of a hydraulic motor based on

concept of a motor that works constantly under same working conditions and has

constant efficiencies .

10

CylModel01A program that simulate double-acting hydraulic cylinder. The model calculates,

interactively, the shown output data

11

ContValve01A program that simulate continuous valve (proportional or servo). The model

calculates, interactively, the shown output data based on the static and dynamic

characteristics reported by the valve manufacturer.
