摘　　要：在Hamilton型拟变分原理体系下,建立了一种时间子域以三次和五次B样条函数插值的时间子域法,并将这种新方法用于单锚腿系泊系统的动力响应分析中。算例表明,新方法比传统的动力计算方法Wilson-θ法,在计算精度上有明显的优势,表明本方法能够用于计算单锚腿系泊系统的动力响应。Based on the Hamilton-type quasi-variation principle, a new method is introduced in this paper. It applies the cubic and quintic B-spline function as interpolation to the time subdomain. Calculated two Single Leg Anchor Mooring Systems dynamical response, the results indicates that the accuracy is better than the Wilson-θ approach. The good agreement of compu- tational results with experiment shows that this new method can sever to compute dynamical response of the Single Leg Anchor Mooring System.
