Original abstract

The turbocharger is a unique example of the rotating machinery. Not only for its very high speed, but also because of its compact design and difficult operating conditions (i.e. high temperature, harsh vibrations, etc.). Moreover, measuring of most parameters characterizing the rotor dynamics is a very difficult task. Thus, it is advantageous to replace the real turbocharger by computational model and determine the turbocharger rotor dynamics using simulation tool. The development of such tool will be presented in this paper.

Czech abstract

Turbodmychadla je unikátním příkladem rotačního stroje. Nejen pro své velmi vysoké otáčky, ale také kvůli své kompaktní konstrukci a obtížným provozním podmínkám (tj vysoké teploty, silné vibrace, atd.). Navíc měření většiny parametrů charakterizujících dynamiku rotoru je velmi obtížný úkol. Proto je výhodné nahradit skutečné turbodmychadlo výpočetním modelem a určit dynamiku rotoru turbodmychadla pomocí simulačního nástroje. Vznik takového nástroje je popsán v tomto dokumentu.
