摘　　要：文章介绍了研制的多向不规则波造波机系统,由20块造波板组成,安装在7 m宽、160 m长的船舶拖曳水池中,利用边壁反射原理,在整个试验区内都可产生多向的不规则波。采用了分段造波的技术以配合拖曳水池中拖车的工作,同时实现了在拖车上遥控造波的功能。实际模拟波浪结果表明,在水池的不同位置模拟的多向不规则波,其实测频谱和方向分布与理论曲线非常接近。多向不规则波传播试验结果表明,该造波机系统可在整个水池试验区内产生所要求的多向不规则波,能够满足科学试验使用要求。A new kind of wave maker system with multidirection irregular wake capability is designed. The system is composed of 20 wave paddles and is installed in the towing tank with 7m height and 160 m length. Using sidewall reflective theory, the multidirection irregular wave is produced in whole experimen tal area. Segmented wavemaking technology is used and teleeontrol function is provided. At last, the simu lating wave experiments were conducted and multidirection irregular waves were simulated on different ar eas. The simulation results show that spectrum and directional distribution of multidirection irregular waves produced on different areas in tank were very close to theoretical curve. The experiment shows the system presented in this paper has good stability to product multidirection irregular wave, and can meet the ex perimental requirements.
