Анализ локализации напряжений при колебаниях рабочих колес и охлаждаемых лопаток ГТД
Анализ локализации напряжений при колебаниях рабочих колес и охлаждаемых лопаток ГТД
Natural vibrations of bladed wheel of gas-turbine engine are considered. Influence of taking in account effects of mutual sliding of band shelves on dynamic characteristics of wheel are provided. Single crystal structured blade with cooling channels system of whirl matrix type is investigated. Influence of crystallographic orientation directions variation on vibration parameters, such as natural frequencies, mode shapes, stress intensities, is estimated.
