Stability analysis of a substructured model of the rotating beam

摘要: One of the most well-known situations in which nonlinear effects must be taken into account to obtain realistic results is rotating beam problem. This problem has been extensively studied literature and even become a benchmark for validation formulations. Among other approaches, substructuring technique was proven valid strategy this Later, similarities between absolute nodal coordinate formulation were demonstrated. At same time, it found existence critical angular velocity, beyond system becomes unstable that dependent on number substructures. Since dependence velocity not so far clear, paper tries shed some light it. Moreover, previous studies focused constant analysis where Coriolis forces neglected. In paper, influence force term The reference conditions element frame are also investigated paper.
