混流式水轮机疲劳设计中的载荷频率影响系数

The Factor of Load Frequency for Fatigue Design of the Francis Tutbine

载荷频率影响系数是关于水轮机疲劳设计的重要设计系数,本文介绍了针对混流式水轮机的载荷特点进行的载荷在单一频率和双频频率作用下的频率影响系数的试验研究,及确定该系数的方法。

The factor of load fre■uency is an important factor for fatigue design of water turbine. This paper introduces the research and test results for the factor under single-frequency and dual-frequency loading, according to the load feature of the Francis turbine. The method to determine the factor is also presented.
