摘要：

Methods to investigate the almost-sure asymptotic stability of non-linear coupled oscillators under external random excitation are presented. Sufficient stability conditions are first derived for ensuring the stability of the rest mode of a vibration-isolating suspension subjected to base excitation by a broad-band random excitation. Necessary and sufficient conditions are later obtained by evaluating numerically the largest Lyapunov exponent of the perturbed responses.
