摘要：

We studied chaotic threshold of a nonlinear dynamical system of beam bridge. The amplification and minification of integral inequality are proposed, which lead to the criteria for chaotic motion directly for the nonlinear system with a half sine pulse excitation avoiding the conventional approximation methods to retain the nature characteristics of the system. The efficiency of the criteria for chaotic motion obtained by use of the Melnikov's method is verified via the bifurcation diagrams, Lyapunov exponents and numerical simulations.
