| 摘要: | 针对海工实验波流水槽中的造流装置与造波装置间存在的干扰问题, 研发了推摇组合式造波的波流循环水槽, 并分别从造流和造波两个方面进行了设计和验证. 综合设计循环流道、造流驱动装置及稳流出水口, 保障实验区域水流稳定性及可控性; 采用倒挂式摇摆结构, 结合平行四边形结构运动特点, 实现倒挂推摇组合式造波, 在保证波形质量的同时减小对流道的影响; 建立数学模型分析推块运动与波浪要素间的关系; 基于西门子PLC开发实验测试平台测控系统搭建整个实验平台, 完成水槽各项性能测试. 结果表明, 实验平台能够实现最大流速1.5m∙s–1, 且同时满足造波周期1~4s, 波高范围0.1~0.6m的单独造波及所需要的波流海况耦合, 能满足相关科教应用要求. |
| Abstract: | In view of the interference between the flow making device and the wave making device in the experimental wave flume, a wave-current circulating flume with push-shake combination is developed. The design and verification are carried out from two aspects of flow making and wave making respectively.The circulation channel, flow making drive device and steady-flow outlet are designed comprehensively to ensure the stability and controllability of water flow in the experimental area; The upside-down swing structure is adopted, combined with the movement characteristics of parallelogram structure, to realize the upside-down push-swing combined wave making, so as to ensure the waveform quality and reduce the influence on the flow channel. A mathematical model is established to analyze the relationship between the push block motion and wave elements. Based on Siemens PLC, the measurement and control system of experimental test platform is developed, and the whole experimental platform ias built to complete the performance tests of the flume. The results show that the platform can realize the maximum flow velocity of 1.5m∙s–1 alone, the period of 1-4s, the wave height range of 0.1-0.6m and the required wave-flow coupling, which can meet the relevant scientific and educational application requirements. |
