    Abstract: 在理想流體及低航述的假定下,將浮體在任意方向的波與流作用下之運動方程式予以簡
    化。簡化後之新的運動方程式的基本解可以格林函數之形式被表示為G:::::G0 + G1 ; 其中
    G0是一震盪源,為零航速情況的基本解;G1 相當于航遠的存在而出現的修正項。最後利用
    這個基本解求解方程。文中以半球為例進行了計算,數值解並與理論值進行比較。結果顯
    示,本方法可以正確的估算低航速浮體在波與流以及波浪阻尼作用下的各運動響應。
    Under the assumptions of potential theory and low moving speed, the equations of a body advancing in waves are simplified. A form of the Green function for the simplified equations is expressed as G.apprxeq.G/sub 0/+.tau.G/sub 1/. It consists of Green function of an oscillating source at zero forward speed, G/sub 0/, and a correction term for low forward speed, G/sub 1/. It has been found that this form has good numerical performance. To test the present method it is applied to a hemisphere. The numerical results of the present method will be compared with the analytical solutions. The approach may offer a decent method in obtaining body responses due to low moving speed while wave damping effects are considered.
