Subject aims expressed by acquired skills and competences

Perfectly describe the properties and behavior of hydraulic and pneumatic components, both in steady state and in dynamic conditions. To analyze the behavior of hydrostatic and pneumatic systems using modern methods of mathematical modeling and computer simulation. To increase the knowledge of control of systems, and hydrostatic and pneumatic control components and systems. To increase the knowledge of the problems of energy balance and hydrostatic systems to identify options for increasing the effectiveness of these systems.

Summary

Studující se nejprve podrobně seznámí s vlastnostmi hydraulických a pneumatických prvků včetně pracovních kapalin hydraulických systémů. Na základě těchto znalostí se bude zabývat analýzou vlastností typických hydrostatických systémů: hydrostatickými systémy s akumulátory, hydrostatickými systémy s proporcionálním řízením, energeticky úspornými hydrostatickými systémy, způsoby řízení hydrostatických systémů apod. Nejčastějšími aplikacemi hydrauliky a pneumatiky u strojů jsou pohony a převody strojů. Postupně je probírána kinematika a dynamika tekutinových pohonů, energeticko-tepelná bilance, vícemotorové pohony a synchronní chod hydromotorů, manipulace s hmotnou zátěží, hydrostatické a kombinované převody, pneumatické pohony a pneumatické řídicí systémy.
