| 中文摘要: |
| 结合研制的伺服电机驱动的主动吸收式造波机,介绍了造波机系统的组成和控制原理．在一阶推板吸收造波理论的基础上,给出了带有造波板反射参数的主动吸收算法,并通过物理模型试验,测试了造波机对周期在1.2~2.4 s的规则波和不规则波的吸收性能．采用两点法对入反射波进行分离,结果表明,理论反射系数与实验值基本一致,对不规则波吸收效率在84%以上． |
| 英文摘要: |
| The system composition and the control algorithm of an active absorbing wavemaker system
are described based on servo motor. An active absorption algorithm with the reflection
coefficient of the wavemaker is presented based on the first-order piston active absorbing
wavemaker theory. And experiments with regular and irregular waves are carried out in wave
period range of 1.2 s to 2.4 s. Separating the incident and reflected waves with two-point
methods, the experimental results show a good agreement between predicted theoretical
reflection coefficient and experimental value, and the absorption efficiency of irregular
waves is greater than 84%. |
