摘　　要：涡轮增压器在航空航天、船舶、汽车等工业已经大量的应用,其中涡轮是较为重要的构件,目前对涡轮强度的分析还较少。根据涡轮增压器研制要求,利用MSC.Nastran对该涡轮增压器轴流涡轮在最高结构转速及温度场耦合作用下涡轮的应力、位移情况,并且考虑涡轮前后不同进出温度温度对涡轮的影响。经过分析,涡轮及叶片在不同温度和最高转速作用下,并未发生屈服,满足力学安全性,为该涡轮增压器轴流涡轮的设计、制造提供参考。At present,there are few analysis on turbine strength with the turbines that it is most important part of the turbochargers it has been widely used in aerospace,ship,automobile and other industries.According to the development requirements of the turbocharger,the stress and displacement of the axial flow turbocharger under the coupling effect of the maximum structural speed and temperature field were analyzed by using MSC.Nastran software,and the influence of different inlet and outlet temperatures on the turbine was also considered.Through analysis,the turbine and blade did not yield under the action of different temperature and maximum speed,which met the mechanical safety,and provided a reference for the design and manufacture of the axial flow turbine of the turbocharger.
