Abstract
This paper deals with obtaining accurate eigenvector derivatives in damped vibration systems with modal truncation method only by system matrices and a few available lower modes. A numerical example shows that the method of t his paper is correct and efficient. (C) 1999 Elsevier Science Ltd. All righ ts reserved.
