GPU Implementation for Wilson-θ Method
2009 Edition, December 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The GPU implementation for Wilson-θ method computing the dynamic response of structures is presented. We use a four-channel, two-dimensional texture to represent a matrix and a vector, and present a new texture reduction algorithm not requiring the texture...

Stability and Bifurcation of Flexible Rotor System with Hydrodynamic Bearing Supports
2009 Edition, Volume 2, April 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Nonlinear dynamic behaviors of hydrodynamic bearing-flexible rotor system are analyzed. A local iteration method consisting of improved Wilson-θ method, predictor-corrector mechanism and Newton-Raphson method is proposed to calculate nonlinear dynamic responses....

Calculation of different damping ratios response spectra by cosine transform
2011 Edition, June 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A new method using cosine transform to calculate response spectra from strong motion earthquake records is developed. Compared to Exact, Wilson-θ and Newmark method, the proposed method has a higher accuracy in displacement and velocity response spectra under...

Modified Wilson-theta Method under State Feedback and Its Calculation Stability
2013 Edition, June 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, using system's dynamic equilibrium equation to determine the imbalance component of calculation acceleration in Wilson-θ integration algorithm, then react to original system as feedback to revise the computational movement state. Two approaches are presented: to revise...
