Theoretical background for identification of the technical condition of avionic hydraulic drives on the basis of information from means for unbiased flight control of aircrafts
Past experience demonstrates that among all commonly known physical phenomena affecting the technical condition of hydraulic units, the following can be distinguished as the most important ones [3, 4]:
– mechanical deterioration of hydraulic plunger and barrel mating assemblies due to abrasive and erosive wear of their working surfaces (Fig. 1),
– fatigue wear of individual components exposed to the impact of dynamic loads,
– ageing of materials, in particular sealing and packing stuff of any type made of elastomeric rubber, caused by various substances used for operation of the units.

It has the advantages of clear force transmission, good integration, flexibility of space separation, as well as reducing of the quantity of material used, full use of the function of the material and structure, and lowering the project cost.
The characteristic parameter of restoring force model is average value of the material strength, which can reflect the real structure condition in practice.

In the process of Preprocessor, material properties such as Poisson ratio, density and so on must be defined according to reality, the next step is to mesh the objective with suitable mesh method which makes the objective ready for FEM analysis.
To be noted that the material of Slider is different from that of guide screws shown in Fig. 1.
So in preprocessor, material properties should be specified according to reality.
