摘要

波浪能液压转化系统采用圆柱浮体垂荡运动激励液压缸,液压缸活塞往复振荡将波浪能转化成液压能,经过调节阀组和蓄能器储存输入液压马达,马达驱动发电机转化成电能。建立不规则波浪作用圆柱浮体并激励液压缸活塞的时域动力模型,建立液压系统蓄能器和马达能量传输及转化模型,研究了液压缸和蓄能器能量转化过程中压力和流量、马达转速和输出功率的动态特性。分析了随机波在液压系统中的能量传输规律和转化效率。
        A wave energy conversion hydraulic system is actuated by a cylinder connected with a cylinder floater. The floater is excited by irregular waves. The wave energy is converted to hydraulic energy through heave motion of cylinder piston. After valve group regulation and an accumulator, a hydraulic motor drives a generator. Dynamic models of the floater and cylinder are established. Energy transfer and conversion models for the accumulator and motor are also set up. Transient pressure, flow rate, motor speed and power take-off are investigated. Conversion efficiency and energy transfer mechanism are analyzed.
