The direct updating of damping and gyroscopic matrices

In this paper we develop an efficient numerical method for the finite-element model updating of damped gyroscopic systems based on incomplete complex modal measured data. It is assumed that the analytical mass and stiffness matrices are correct and only the damping and gyroscopic matrices need to be updated. By solving a constrained optimization problem, the optimal corrected symmetric damping ...

Design of Variable Damping and Stiffness Matrices

amping and stiffness control in a telerobotic system allows the programmer to define the master and slave dynamics to suit a given task. Unfortunately, many requirements for good teleoperation produce conflicting choices of desired dynamic parameters for different tasks. It is proposed here that the master and slave damping and stiffness matrices be functionally dependent on b e n d and command...

The direct updating of damping and gyroscopic matrices using incomplete complex test data

In this paper we develop an efficient numerical method for the finite-element model updating of damped gyroscopic systems based on incomplete complex modal measured data. It is assumed that the analytical mass and stiffness matrices are correct and only the damping and gyroscopic matrices need to be updated.
