一类非线性梁在随机载荷作用下的弯曲振动

非线性工程结构对随机载荷的动力响应分析是当前工程界十分关心的问题,为了解决这类非线性随机振动问题,本文利用Von Karman和Howarth在湍流研究中提出的方法,研究了一类弱非线性等直梁在随机载荷作用下的弯曲振动,给出了一种适用于动力响应分析的,简单而实用的近似方法。

Nonlinear waves and wave-structure interactions in marine hydrodynamics——Recent progress

We briefly review the recent progress in marine hydrodynamics.Developments in wave-structure interaction,wave-current interaction,Rogue waves,sloshing in liquid tanks and their applications in ocean engineering,such as Floating Production Storage and Offloading facility(FPSO) and Very Large Floating Structure(VLFS),are presented.
