摘　　要：基于系统的观点,将键合图方法引入波浪能系统建模与分析,以液压型双体波浪能转换系统为例,构造系统键合图并给出系统状态方程;设置参数进行仿真分析,并通过模型实验对仿真结果的可靠性进行验证,分别对比相对运动位移、液压缸活塞受力和蓄能器出口压力,仿真结果曲线与实验测试结果曲线吻合度较高,各参数相对差值基本控制在5%以内。结果证明键合图法可作为波浪能转换系统设计、优化和评估的重要工具。Based on the system viewpoint,the bond graph method was introduced into the modeling and analysis of wave energy system.Taking the hydraulic two-body wave energy conversion system as an example,the system bond graph was constructed and the state equations were given. The simulation analysis was implemented by setting the parameteys,and then the reliability of simulation results was verified by model experiment. The relative heave displacement,hydraulic cylinder piston force and accumulator outlet pressure were compared respectively. The simulation result curves show a high degree of coincidence with the experimental test results,and the relative difference of each parameter is basically controlled within 5%. Results show that the bond graph method can be used as an important tool for the design,optimization,and evaluation of wave energy conversion systems.
