비보존력을 받는 다수의 집중질량을 갖는 외팔보의 안정성에 관한 연구

A study on the stability of the cantilever beam with several masses subjected to a nonconservative force

본 연구에서는 종등력을 받는 다수의 집중질량을 갖는 외팔보에 대해 집중질 량의 위치, 집중질량간의 집중질량비 및 집중질량대 분포질량의 질량비에 따른 보의 안정성에 관해 연구하였다.

The stability behavior of the cantilever beam carrying several masses and subjected to a follower force at its free end is investigated. The effects of the location and the mass ratio of the concentrated masses on the stability of the system are discussed. An optimal location of the concentrated mass is determined to give maximum critical follower force. Discontinuities of the flutter load are observed for the system with more than two concentrated masses.
