O knihe

In various industrial applications, there is a needfor higher speed, yet reliably operating rotatingmachinery. A key factor in achieving this type ofmachinery continues to be the ability to accuratelypredict the dynamic response and stability of arotor-bearing-seal system. In operation, the rotorundergoes bending and torsional vibration. Thevibration of a rotor depends upon its geometry andtype of support, as well as on the excitation forces.One of the most important sources for excitation isthe flow through labyrinth seals. The gas flowthrough the seals, primarily intended for leakagecontrol in turbines, creates net pressure and shearforces acting on the rotor. It is necessary topredict these forces exactly for reliably operatingturbomachines. This book, therefore, providestheoretical investigation of the gas flow instraight-through labyrinth seals and its effect onthe stability of the rotor. In addition, stability ofrotor-bearing systems is given to introduce andexplain the nature of rotordynamic phenomena fromcomparatively simple analytical models. This bookwill no doubt be of value to graduate students andresearchers in engineering and applied sciences.
