| 摘 要： | 通过对海洋结构物在波浪冲击作用下动力响应的试验研究,分析了波浪冲击作用下结构物最大动力响应及出现的时间。基于Fourier变换的频谱分析,得到了波浪冲击荷载作用下平台结构的水平和竖向振动特性。当入射波频率接近平台水平固有频率时,在水平方向会产生共振。结构物模型竖向刚度较大,试验中竖向不发生共振。

| Abstract: | By the experimental investigation of the dynamic responses of marine structure under wave impact,the largest structure dynamic response and the time of its occurrence were analyzed.Based on the Fast Fourier Transform,the vibration characteristic of the structure model in both horizontal and vertical direction under wave impact was given.When the eigen frequency of the structure falls in the range of the incident wave frequency,it will cause resonance effect.As the vertical rigidity of the structure is very ... |
