✦ Synopsis

A powerful matrix reduction technique is developed to analyze rotor-bearing systems. by using the modal data of the isotropic undamped stationary parts. This method gives significant reductions in computation time and core size, while maintaining accuracy and flexibility in use. It does not require any intuition on masslumping and/or mode selection, iterative procedure to improve the transformation matrix, or substructuring; only minor modifications to existing FEM techniques are required.
