| 摘 要： | 采用多刚体动力学方法建立缆索的力学模型,根据得到的KANE运动力学方程,利用四阶龙格库塔法在时域内进行求解并分析缆索的动力特性。对于单根锚链,采用多刚体法和有限元法进行计算,并将计算结果和相应的试验结果进行比较,验证了多刚体法在锚链动力分析中的可靠性。在此基础上考察多刚体法在钢缆动力分析中的适用性。通过改变链环长度,比较模型缆上端点的张力变化,由计算结果发现对于环长和链长的比值在一定范围内,多刚体法可以用于缆的动力分析。

| Abstract: | Based on the method of muti-body system dynamics,the dynamic model of mooring lines was established.Kane method was employed to obtain the dynamic equations.The dynamic response of the mooring lines can be calculated by the fourth-order Runge-Kutta method.As to chains,the simulation by the multi-body method was carried out.The results were compared with the experimental ones.The comparison results validated that the method is available in the dynamic analysis of chains.The multi-body system dynamics was app... |
