摘　　要：通过分析涡轮叶轮叶片角与反动度的关系,设计了叶片角分布控制参数,构建了3种不同反动度的增压涡轮,匹配不同尺寸的涡轮壳,在相同流量条件下,研究了不同反动度涡轮对涡轮级的性能影响规律。最终,应用基于涡轮反动度特征叶片角分布控制方法,实现了增压器涡轮的全参数化设计。结果表明,采用基于反动度的增压器涡轮叶轮的设计方法是可行的,可以满足增压器涡轮叶轮性能优化设计需求。By analyzing the relationship between the blade angle and degree of reaction(DOR),the control parameter of blade angle was designed,and three turbine wheels of different degrees of reaction were constructed,which matched different volutes.The influence of DOR on turbine performance was investigated.Finally,the full-parameter optimization of turbocharger turbine was realized based on blade angle distribution obtained according to turbine DOR characteristic.The results show that the introduced turbine wheel optimization design method is feasible,which can meet the performance optimization requirements of turbocharger turbine wheel.
