| 摘 要： | 为研究浮体在波浪中的运动，工程中采用基于刚体运动学的理论，应用牛顿第二定律建立了箱体在六个自由度的耦合运动方程。采用修正的切片法计算了箱体在规则波中运动的附加质量、附加阻尼和静水恢复力，并以纵摇和垂荡两个运动模态为例，在频域和时域内计算了浮体在规则波中两个运动模态的波浪载荷和运动响应，并对运动响应特性进行了分析。

| Abstract: | For the motion simulation of a barge in waves, the rigid-body based dynamics theory and the Second Newton Law is usually used in engineering practice to establish coupling motion equations with six degrees of freedom. In this article a modified strip method is employed to deduce the added mass, damping coefficients and restoring force on motions of the barge moving in regular waves. Taking heave and pitch for example, sea load and motions response are predicted for barge moving in regular waves with frequency-domain and time-domain method, and the motion response characteristics is analyzed as well. |
