abstract = {<p style="text-align: justify;">In this paper, the Dirichlet boundary value problems of the nonlinear
beam equation $u_{tt} + ∆^2u + αu + ϵϕ(t)(u + u^3
) = 0, α &gt; 0$ in the dimension one
is considered, where $u(t, x)$ and $ϕ(t$) are analytic quasi-periodic functions in $t$, and $ϵ$ is a small positive real-number parameter. It is proved that the above equation
admits a small-amplitude quasi-periodic solution. The proof is based on an infinite
dimensional KAM iteration procedure.</p>},
