摘　　要：主动式截断混合模型试验技术是一种新兴的海洋工程试验技术,然而由于缆索运动具有较强的非线性特征,时域内系泊缆截断点处的运动往往需要采用数值方法进行迭代求解,运算量十分可观,成为实现主动式混合模型试验技术的障碍。文中提出一种基于Narx网络模型计算时域内缆索截断点处加速度方法,该方法较一般数值方法所需要的计算时间更少且能保证较好的计算精度。Active truncated system is a developling technology for modeling test of offshore platform in wave basin. However, when using numerical method like lumped-mass method to solve the motion problem of truncated point, it is very time-consuming because of the iterative process. In this paper, a method based on the Narx network is used to get the acceleration of truncated point in time domain. Compared with other numerical methods, the new method takes less time to finish camputation progress and can also guarantee good accuracy.
