摘要: 本文用有限元法求解梁的非线性振动问题,发现非线性系统也会发生共振,并给出了其共振频率,为工程设计提供了一个新的依据。

Abstract: The problem of nonlinear resonance of elastic beam is studied by finite element method using a nonlinear factor. It is discovered that the resonance can also take place in this case, the resonant frequency of this problem is given. The study given here shows a new way for engineering design.
