Повышение эффективности формирования цифровых моделей авиационных двигателей для расчетов динамики роторов

Abstract

The paper describes the process of automatic creation of aircraft engine digital model for rotordynamics simulation in software DYNAMICS R4. Developed algorithm automatically retrieves dimensions and geometry of engine parts from their CAD geometry. Application of the algorithm allows significantly faster create large models such as aircraft engine full model as long as minimize number of user’s errors associated with data entry while model creation and measuring of its associated geometry in CAD. Digital model of turbojet engine F-404-GE-400 was created in DYNAMICS R4 for rotordynamics simulation as demonstration of the developed algorithm of automatic geometry CAD import performance.
