摘　　要：车载氢能瓶口阀是氢燃料电池汽车上的关键部件,针对其结构复杂,集成度高问题,介绍了一款特定瓶口阀的设计思路及过程。针对瓶口阀易受外界低频振动影响,建立了瓶口阀的动力学模型,对其固有频率和振型等振动特性作了研究,并通过模态试验进行验证,试验结果与分析结果基本吻合,说明了有限元分析方法的有效性。The on-board hydrogen energy bottle valve is a key component of hydrogen fuel cell vehicles.In view of its complex structure and high integration,this paper introduces the design idea and process of a specific bottle valve.In view of the low frequency vibration of the cylinder valve,a dynamic model of the cylinder valve was established,and its vibration characteristics such as natural frequency and vibration mode were studied,and verified by modal tests.The experimental results are in good agreement with the analysis results,which shows that the finite element analysis method is effective.
