【摘要】：近海結(jié)構(gòu)的研究是海洋工程領(lǐng)域的重要專題。本文以Airy線性波理論和莫里森方程為基礎(chǔ)推導(dǎo)平臺結(jié)構(gòu)的運(yùn)動方程。將波浪力簡化為二節(jié)點(diǎn)集中載荷,從動力學(xué)的角度分析結(jié)構(gòu)的響應(yīng)特征。以一簡化的固定平臺為算例,以不同的入射波為激勵條件分析比較結(jié)構(gòu)的位移響應(yīng)、速度響應(yīng)以及加速度響應(yīng)。研究結(jié)果表明,隨著入射波強(qiáng)度的增大,結(jié)構(gòu)的振動變得更為劇烈,且結(jié)構(gòu)的振動響應(yīng)不僅與入射波的周期和波高有關(guān),與波浪的形式也有一定的關(guān)系。
[Abstract]:The study of offshore structures is an important topic in the field of ocean engineering. Based on Airy's linear wave theory and Morrison equation, the motion equations of platform structures are derived in this paper. The wave forces are simplified as two-node concentrated loads. The response characteristics of the structure are analyzed from the dynamic point of view. Taking a simplified fixed platform as an example, the displacement response, velocity response and acceleration response of the structure are analyzed and compared with different incident waves. The results show that, With the increase of incident wave intensity, the vibration of the structure becomes more intense, and the vibration response of the structure is not only related to the period and height of the incident wave, but also to the form of the wave.
