Theoretical and Experimental Study of Hydro-Elastic Instability on the Line of Shafting of a Rotating Machine

摘要

Following a theoretical study, which concerns the movement of a rotating cylinder partially filled with a liquid on an elastic shaft and formulates it into an equation, the tests are described which allowed the validation of the theory. The effect of different parameters on the stability and behavior of the system are determined (level of liquid, viscosity, speed of rotation, critical speed of the shaft). (ERA citation 10:018877)
