Original abstract
The existing computational models representing working cycles of external heat supply engines are usually based on ideal theoretical cycles, which are modifyied in different ways. The parameters of engines realized on the basis of these models are lower by tens per cent if compared with the calculated data. In order to solve the tasks of control and diagnostics of units consisting of external heat supply engines, computation models of a higher level were necessary. A virtual prototype of the gama-modification Stirling engine is designed in the thermodicamic part as a modular system comprising generalized volume elements; engine mechanism and mechanical structures including floating mounting are modelled as multi-body.
Czech abstract
Dosavadní výpočtové modely pracovních cyklů motorů s vnějším přívodem tepla vycházejí zpravidla z ideálních teoretických oběhů, které pouze různým způsobem modifikují. Parametry motorů realizovaných na základě těchto modelů jsou obvykle oproti vypočteným hodnotám nižší až o desítky procent. Pro řešení úlohy řízení a diagnostiky soustrojí s motory s vnějším přívodem tepla bylo nezbytné vypracovat výpočtové modely vyšší úrovně. Virtuální prototyp Stirlingova motoru gama-modifikace je v termodynamické části koncipován jako modulární systém sestavený ze zobecněných objemových elementů, mechanismus a mechanické struktury motoru včetně pružného uložení jsou modelovány na bázi multi-body systémů.
