摘要：
In this paper, frequency characteristics of a flexible hub-beam system with an attached mass are studied using a first-order approximation coupling (FOAC) model. Based on the Hamilton principle and finite element discretization method, expression of FOAC model for flexible hub-beam system is presented, then frequency characteristics with different position and weight of attached mass are studied through numerical simulations. Numerical results indicate that, along with lapsing of attached mass from fixed end of beam, vibration frequency of beam is not degressive when the mass is in front half part of beam, and it shows an obvious degressive trend when the mass in back half part of beam.
