摘　　要：系泊船舶的水平慢漂运动的自然频率远低于一阶运动的自然频率。本文对具有这一特性的模型试验中不规则波浪模拟所必需包含的成分波个数与系统的自然频率关系作了研究,并提出了在不规则波模拟中波频的分割间隔与系统的自然频率关系的准则。通过模拟计算并用三种不同方法产生的不规则波所得到的模型试验结果证实,凡符合这一准则,得到的模型试验结果是可靠的、否则将产生严重失真。The natural frequency of horizontal drift of moored systems is far lower than that of the first order motion. Based on the investigation of the relationship between the natural frequency and the component number of simulated irregular waves, the authors present a criterion concerning the relationship between the natural frequency of the system and the separation interval of wave frequencies. The computational simulation and the model tests by means of three different methods for generating irregular waves show that the model test results are reliable in case complying with the criterion mentioned above.
