Operating Modal Analysis of Mobile Wastewater Treatment Plant


Article Preview

To reduce the noise and vibration of mobile wastewater treatment plant, this paper presents testing and analysis of 50 measuring points in the working state of mobile wastewater treatment plant based on TST test analysis system. The structure’s natural frequency, damping and modal vibration modes are extracted within the frequency band of 0-1000HZ. By comparing the operating modal and the finite element modal, it is believed that the operating modal can accurately recognize modal parameters of the container.
