| Abstract: | For a turbocharged diesel engine,the working process of diesel engine was simulated with the GT-Power software and the rules of state parameters were acquired.In certain conditions,the fluid-thermal coupling of turbine was analyzed and the thermal and aerodynamic loads during the working process were acquired.In addition,the turbine stress responses at centrifugal loads,thermal loads and aerodynamic loads were researched,the stress distribution at different loads was calculated and the mechanisms of different stress states were analyzed.Finally,the influence degrees of different loads on turbine stress response were researched. |
