Generalized Coordinates Affected by External Term in Structural dynamics Analysis : 1st Report, Basic Concept and Calculation Scheme of Presented Generalized Coordinates

Abstract

The effectiveness of a correction method using static response as an approximate solution for response values of higher modes has been presented by O. E. Hansteen. In this paper, a method is presented in the form of generalized coordinates, for the purpose of extension to component mode syntheses or a free-free (incompletely supported) system. The basic concept of the generalized coordinates and calculation algorithms are shown. External term error estimation is then considered, when generalized coordinates are employed. Two models are used to verify that the error norm of external load vectors is close to zero (less than 10^-4).
