【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。更多还原

【Abstract】 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 computational results with experiment shows that this new method can sever to compute dynamical response of the Single Leg Anchor Mooring System.更多还原
