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.
