| Abstract: | Matrix perturbation essentially deals primarily with the effects of the small changes in structural parameters on the vibration modes. This paper is concerned with the applications of matrix perturbation in vibration engineering, such as sensitivity analysis of vibration modes in dynamic optimization designing, and accuracy estimation in Guyan reduction. |
| |
| Keywords: | perturbation method vibration modes sensitivity. |
