摘要
车载氢系统作为燃料电池汽车的核心子系统之一,在交通事故中,一旦承受较大的挤压力,可能导致关键零部件发生功能失效,进而引发氢气的大量泄漏,造成更严重的后果,对车载储氢气瓶进行耐挤压性测评是进一步完善燃料电池汽车安全评价体系的重要工作。建立了车载储氢气瓶的挤压测评方法,详细阐述了挤压测评方法 4方面的内容,并进行了车载储氢气瓶的挤压试验验证,通过试验数据分析挤压对储氢气瓶的影响,定量评价分析储氢气瓶挤压之后的安全性,为车载氢系统安全评价提供参考。
As one of the core subsystems of fuel cell vehicles,the on-board hydrogen system,once subjected to a large extrusion pressure in traffic accidents,may lead to the failure of key compo-nents,resulting in a large amount of hydrogen leakage,which may lead to more serious consequences,so the evaluation of the extrusion resistance of the on-board hydrogen storage cylinders is an important task to further improve the safety evaluation system of fuel cell vehicles.This paper establishes a squeeze evaluation method for on-board hydrogen storage cylinders,describes in de-tail the four aspects of the squeeze evaluation method,and carries out the squeeze test verification of on-board hydrogen storage cyl-inders,analyzes the impact of squeezing on the hydrogen storage cylinders through the test data,and quantitatively evaluates and analyzes the safety of the hydrogen storage cylinders after squeez-ing,so as to provide a reference for the safety evaluation of the on-board hydrogen system.
