Abstract

以摆动扑翼波浪能发电装置的液压转换系统为研究对象,设计了一种包含多腔油缸的液压转换系统,将波浪能转换为可用的机械能。基于液压转换系统高效采集随机波和稳定输出的原理,设计了多腔油缸,确定了液压转换系统的组成及各部件的具体参数。根据不同的海况,通过控制开关阀的组合状态实现随机波浪的采集,设计调整蓄能器的数量和预充压力,保持液压系统高低压管路压力稳定,液压马达能够稳定输出机械能。基于多能量域键合图建模理论,利用系统仿真仿真平台对采集机构和液压转换系统进行建模。作为系统输入,仿真了采集机构在三级、四级和五级海况下的运动响应。对液压转换系统的有效性、输出稳定性和转换效率进行了仿真分析。结果表明,通过控制开关阀的组合状态,所设计的液压转换系统能够有效地采集随机波,有效地提高了液压转换系统的稳定性和转换效率。研究结果为振荡扑翼波发电装置液压转换系统的开发和研究奠定了理论基础。
