摘要
利用连续线性系统的随机振动理论,引入结构微分算子,采用模态叠加法,研究了粘弹性梁在随机干扰下的动力反应问题,详细研究了在平稳随机干扰情况下的梁的动力可靠度。
Using the stochastic vibration theory of continuative linear system and introducing differentiating operator of construction, this paper studies the dynamic response problem of viscoelastic beam in stochastic disturbance using modality superposition method. Dynamic reliability of beam is studied under stationary stochastic disturbance in detail.
