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...

A SHAPE-FINDING ANALYSIS OF SUSPENDED STRUCTURES ON THE DISPLACEMENT-METHOD EQUILIBRIUM
shape finding displacement method elastic catenary iteration
2008/12/26
By its geometrical nonlinearity, the realization of a desired suspension structure depends on the shape-finding procedure. In an actual suspension structure, cable members are usually combined with b...
