Pasternak 탄성지지 하에서 비보존력계의 동적 안정성해석
Dynamic Stability Analysis of Non-conservative Systems under Pasternak Elastic Foundations
초록
Mass matrix, elastic stiffness matrix, load correction stiffness matrix by circulatory non-conservative force, and Winkler and Pasternak foundation matrix of framed structure in 2-D are calculated for stability analysis of divergence or flutter system. Then, a matrix equation of the motion for the non-conservative system is formulated and numerical results are presented to demonstrate the effect of some parameters with using Newmark method.
