Vibration Monitoring of Steel Shaft Headgears
Abstract The structures of shaft headgears belong to the high responsibility class of structures, which have a requirement regulatory - monitoring equipment for technical condition. Due with the dynamic tone of operational loads, for the construction of shaft headgears is relevant to create vibration monitoring systems. In the experimental researches of dynamic behavior of shaft headgears structures, were applied measuring method of vibration parameters by vibration transducers. Long-term observations of peak values of vibration velocity amplitudes were statistically processed and established by distribution laws of their random variables. Comparison of the obtained amplitude-frequency characteristics of general vibration structures with the results of modal analysis was made. In this article a rational scheme of the vibration transducer location in the upper part of the structures is proposed. Based on long-term statistical data analysis observations of the peak values of the vibration amplitudes the criterion for determining the limiting values of the vibration speed amplitude is formulated. But exceeding of that is a diagnostic sign of unsatisfactory technical condition of the structure. That are under condition of the spectrum deviation of own frequencies from the reference. The concept of vibration monitoring of shaft headgears structures is formulated, which is based on the comparison of constantly measured vibration speed amplitude with boundary values, and also on the control of the spectrum of the own frequencies oscillations.
