伪随机激振是结构模态试验的一种有发展前途的方法。本文叙述了Monnte Carlo方法在微机上生成伪随机信号的原理;论证了生成信号的平稳性及各态历经性;分析了
Pseudo-random excitation is a promising method for structural modal testing. This paper describes the principle of the Monnte Carlo method to generate pseudo-random signals on a microcomputer. The stability and the ergodicity of the generated signals are demonstrated.
