摘　　要：柔性管构件波浪能装置在波浪的激励下可以形成激突波,从而产生振荡流,驱动涡轮机构产生能量。为研究该柔性管构件波浪能装置的关键特性,在水槽中分别对其进行了相关的模型试验,包括柔性管的膨胀率测量试验、静水中活塞机构推动试验以及规则波作用下试验。试验发现了在活塞推动下,管内激突波的周期与活塞推动的周期始终近似成倍数关系;计算了柔性管在规则波作用下管内激突波的波速,得到了当管内速度与管外波速相近时,装置右端管内波面升高较大,其产生能量也较大。The wave energy device of flexible pipe components can form excitation wave under excitation of waves,thus generating oscillating flow,while the turbine mechanism generates energy.In order to study the key characteristics of the wave energy device of flexible pipe components,the relevant model test was carried out in the tank.The model test covered the measurement of expansion rate of a flexible tube,the experiment of the piston mechanism in still water and the experiment in the regular wave.It is proved that the period of the excitation wave generated in the case of the piston is always approximated by the time of the piston peri?od.The velocity of the excitation wave in the flexible pipe under the action of regular wave is also calculated.When the velocity of the excitation wave is similar to that of the incident wave,the higher the elevation of wave is,the more the energy is produced.
