摘要：
According to the structural characteristics and operation profiles of radial turbines, the spatial distribution characteristics of load and stress of turbine blades were analyzed. For the failure mode of blade root fracture caused by fatigue and creep, the loadings and stress processes of blade roots of turbines were studied, and the methods for describing the load and stress of turbine blade roots were developed. Then, the life prediction methods of turbine blade root of turbochargers were studied and the life prediction model of turbine blade roots with the failure mode of fatigue and creep was derived. Finally, taking the turbine of turbocharger for automobile diesel engine, the model built was applied to analyze the life of turbine blade roots of turbocharger for vehicle applications. © 2019, China Mechanical Engineering Magazine Office.
