Vibration analysis of rotating twisted and open conical shells
TL;DR: In this article, a numerical method for free vibration of a rotating twisted and open conical shell is presented by the energy method, where the effect of rotation is considered as initial deformation and initial stress resultants which are obtained by the principle of virtual work for steady deformation due to rotation.

Frequency analysis of centrifugal fan impellers
P. Balasubramanian,V. Ramamurti +1 more
TL;DR: In this article, the natural frequencies of centrifugal fan impellers were determined by solving tridiagonal block matrices, and the simultaneous iteration scheme was modified to extract the natural frequency from the resulting complex eigenvalue problem.

Geometric Nonlinear Vibrations of Rotating Variable Thickness Plates Induced by Periodic Incoming Wakes
TL;DR: In this article, a periodic incoming wake mathematical model was developed to consider the influence of pressure variations on turbomachines, considering thickness variations along both the chord to reduce vibrations and the span to decrease centrifugal stress.
Parallel processing for nonlinear dynamics simulations of structures including rotating bladed-disk assemblies
TL;DR: There are contributions to four main areas: finite element modeling and analysis of rotational dynamics, numerical algorithms for parallel nonlinear solutions, automatic partitioning techniques to effect load-balancing among processors, and an integrated parallel analysis system.
