根据相似理论原理,设计模化型汽轮机调节阀。通过试验,并利用探索出来的适合于汽轮机调节阀随机过程的频谱分析与动态信号处理方法,最终得到阀杆轴向振动是由阀碟下方的压力脉动引起的低频强迫振动。
According to the principle of similar theory, the design of the model steam turbine control valve. Through the experiment and the exploration of spectrum analysis and dynamic signal processing methods suitable for the random process of steam turbine regulating valve, the axial vibration of the valve stem is finally obtained as the low-frequency forced vibration caused by the pressure pulsation under the valve disc.
