摘要

摘要我们考虑了沿水平轴受拉梁的准线性欧拉-伯努利振动方程的时间周期解问题。边界条件分别对应于弹性固定端、夹紧端和铰链端。非线性项在无穷远处满足非共振条件。利用 Schauder 原理，我们证明了周期解的存在性和唯一性定理。

Periodic Solutions of the Euler–Bernoulli Quasilinear Vibration Equation for a Beam with an Elastically Fixed End

Abstract

We consider the problem about time-periodic solutions of the quasilinear Euler–Bernoulli vibration equation for a beam subjected to tension along the horizontal axis. The boundary conditions correspond to the cases of elastically fixed, clamped, and hinged ends. The nonlinear term satisfies the nonresonance condition at infinity. Using the Schauder principle, we prove a theorem on the existence and uniqueness of a periodic solution.
