基于 NURBS 方法研究了船舶随浪航行纯稳性损失问题。首先对 NURBS 曲线曲面算法和船体表面网格自动化分的原理方法进行了研究，给出了船体表面网格自动化分的算法。随后建立了船舶随浪航行的瞬时平衡方程，通过牛顿迭代法求解该非线性方程，最后编制计算程序，对船舶随浪稳性问题进行计算，分析了波长、波高、浪向角和波浪与船舶的相对位置，以及参数耦合作用对船舶随浪稳性的影响。

Pure loss of stability of ships in following waves is studied in this paper. NURBS algorithm for curves and surfaces is studied. An algorithm for automatic generation of meshes for ship hull is given. Instantaneous equilibrium equation of ships in following waves is established and solved with Newton's iterative method. A computer program is developed for analyzing the stability of ships in following waves. Wave factors influencing ship stability in following waves, such as wave length, wave height, wave direction, etc., are analyzed.
