Abstract: Hirth coupling transmits high torques in the rotating assemblies of compressors and turbines. Their mating surface contacts cause local changes in lateral shaft stiffness. This is affected by the teeth geometry, contact ...

Abstract: Abstract. Accurately predicting critical speeds and shaft dynamic responses to imbalance is essential in rotordynamic analysis. Comprehensive simulations must be performed prior to manufacturing gas turbines or jet engines ...

Abstract: The rotating assemblies of critical machinery are complex dynamical systems and rotordynamic model response prediction inaccuracy risks machinery failure leading to high production losses. Jeffcott, Euler beam, and ...

Abstract: Conventional rotordynamic analyses generally treat the rotor as a continuous body without considering effect of clamped joints. However, in modern rotating machines, rotors are often assembled with multiple complex-shaped ...
