具有Kelvin-Voigt阻尼的非线性轴向运动弦的稳定性

Stability of a Nonlinear Axially Moving String With the Kelvin-Voigt Damping

Shahram M. Shahruz

摘要:

本文研究了具有Kelvin-Voigt阻尼的轴向运动非线性弦线。证明了弦是稳定的,即,当弦的轴向速度小于某一临界值时,其横向位移收敛为零。证明是通过证明对应于弦的李雅普诺夫函数指数衰减到零来建立的。它还表明,字符串位移有界时,有界分布的力施加到它的横向。此外,几个开放的问题,关于稳定性和稳定的Kelvin-Voigt阻尼的字符串的陈述。

英文摘要:

In this paper, a nonlinear axially moving string with the Kelvin-Voigt damping is considered. It is proved that the string is stable, i.e., its transversal displacement converges to zero when the axial speed of the string is less than a certain critical value. The proof is established by showing that a Lyapunov function corresponding to the string decays to zero exponentially. It is also shown that the string displacement is bounded when a bounded distributed force is applied to it transversally. Furthermore, a few open problems regarding the stability and stabilization of strings with the Kelvin-Voigt damping are stated.
