Virtual engineering in the turbocharger stresses analysis

Abstract

The article presents questions connected with the problems of turbocharger turbine wheel dynamic stresses modelling with utilization of CAD environment. The paper enclose some aspects of turbine wheel profile with regard of material, work condition and most frequent damages type which appears in case of faultily realized exploitation procedure of the charging device. The most popular methods of turbocharger selection for combustion engines were mention in the paper. The main part of the work includes the turbine wheel stress analysis and turbine wheel blades strain. The virtual analysis was conducted for three types of turbine wheel: cars, delivery truck and motor truck. The main aspect during the planned strength tests it was a representation of complicated shapes, curvatures of the rotor blades. In the research included heat transfer by convection applied. Introduced in this paper investigations confirm that virtual tools used for modelling aided the investigative process of turbine selection on the construction stage in range of stresses analysis, displacement and final shape of turbocharger.
