浮体绳轮波能采集技术的研究与试验
|
摘要
采用滚动导管机构消除前期浮体绳轮波能装置主绳缆与导绳器间的接触和磨损,利用真空气缸收绳机构提高装置的收绳能力和可靠性。为研究改进后浮体绳轮波能装置的采集效率,基于有限水深Airy波理论和莫里森方程,利用Aqwa和Orcaflex进后浮体绳轮波能装置的质量、阻尼系数、收绳力等关键参数进行优化。常见海况下的优化计算结果表明:改进后的浮体绳轮波能装置具有较高的波能采集效率,且小浪下的装置最优采集效率高于大浪下的装置最优采集效率。
The vacuum cylinder technology is used to improve the ability and reliability to retrieve the rope in the prefloating rope pulley wave energy device,and the guide rod technology is used to eliminate contact and wear between the main cable and rope guide. In order to study the gathering efficiency of the reconstructive wave energy device,based on the finite water depth Airy wave theory and Morrison equations,and the maximum wave energy gathering efficiency taken as the optimization target,the key parameters of the reconstructive buoy-rope-drum wave energy device,such as the quality,damping coefficient and rope pulling force,are optimized by using the Aqwa and Orcaflex. The optimization results in the three common sea conditions show that the reconstructive buoy-rope-drum wave energy device has higher wave energy gathering efficiency,and the wave energy gathering efficiency in small waves is higher than that in big waves.
