摘要
为了正向开发纯氢燃料电池热电联供系统,对燃料电池系统各模块进行集成,并利用UG对支撑燃料电池系统各模块的主机架进行模态分析。以某10 kW纯氢燃料电池热电联供系统为研究对象,首先,对燃料电池系统各模块进行空间设计与集成;其次,利用模态有限元分析对支撑燃料电池系统各模块的主机架进行结构仿真,得到热电联供用纯氢燃料电池系统主机架的前六阶模态参数,同时分析空压机、水泵等激励对主机架整体构架的影响。结果表明:激励源能够在控制方式和安装位置方面避开共振的发生,热电联供用纯氢燃料电池系统主机架设计合理,具有较强的稳定性和可靠性,为后续设计及优化提供理论参考依据。
In order to develop the pure hydrogen fuel cell combined heat and power system,the modules of the fuel cell system are integrated,and the modal analysis of the main frame supporting each module of the fuel cell system is carried out by UG.Taking a 10KW pure hydrogen fuel cell combined heat and power system as the research object,firstly,the space design and integration of each module of the fuel cell system are carried out;secondly,the structure of the main frame supporting each module of the fuel cell system is simulated by modal finite element analysis,and the first six modes of the main frame of the pure hydrogen fuel cell combined heat and power system are obtained.At the same time,the influence of air compressor,water pump and other excitation on the overall frame of the main frame is analyzed.The results show that the excitation source can avoid resonance in control mode and installation position.The design of the main frame of pure hydrogen fuel cell combined heat and power system is reasonable and has strong stability and reliability,which provides a theoretical reference for subsequent design and optimization.
