摘　　要：系统分析了车用涡轮增压器涡轮非稳态特性测量及计算的方法,提出了涡轮瞬态实际输出功等影响涡轮非稳态特性获取的关键参数的得出方法,探讨了试验中不能直接测量的参数的获取方法和测量瞬态参数时间不同步问题的解决方案,为涡轮的非稳态特性测量及计算提供理论支持;在此方法的基础上,搭建了涡轮非稳态特性试验台,研制了脉冲发生器并提出了脉冲发生器系统的设计方法,为涡轮的非稳态特性研究提供了一种有效的试验手段;对某型号涡轮工作在发动机典型工况下的特性进行了试验研究,观察到了"涡轮非稳态特性圈"现象。The measurement and calculation method of turbocharger turbine unsteady characteristics were analyzed systematically. Then the method of acquiring key parameters like turbine transient output power was put forward. Simultaneously, the method of acquiring indirect measurement parameters and the time asynchrony of measuring transient parameters were discussed, which laid the foundation for the unsteady measurement and calculation. Finally, the turbine unsteady characteristic test bench was built and the pulse generator and its design method was developed, which brought an effective method for turbine unsteady characteristic research. By researching the turbine characteristic of engine typical conditions, the phenomenon of ＂close loop characteristics＂ was found.
