The present paper develops a new method for damage localization and severity estimation based on the employment of modal strain energy. This method is able to determine the damage locations and estima...
A VIBRATION FINDING SURVEY OF EXISTING STEEL PENSTOCKS AND NATURAL FREQUENCY CALCULATION FORMULAE
steel penstock pressure pulsation resonance numerical analysis
2009/1/4
When a momentary pressure pulsation takes place in a turbine, and its frequency coincides with the natural frequency of a steel penstock, resonance occurs resulting in noticeable vibration. While the...
