车载储氢系统在使用过程中不仅要确保氢气的高效利用，还要保证在车辆行驶过程中相关振动安全性。通过ABAQUS软件采用随机响应的分析方法，对储氢系统进行随机振动模态分析，并基于模态分析与频率响应分析，以储氢气瓶组外部支撑框架为随机振动疲劳分析的研究对象，通过Fe-safe软件提出一种基于随机振动的疲劳寿命计算方法，对某车用储氢系统框架进行随机振动疲劳寿命性能分析。得到储氢系统在X(车左右)、Y(车上下)、Z(车前后)方向的储氢系统框架随机疲劳寿命结果。表明在X方向上不会发生疲劳失效，在Z方向和Y方向同一位置(瓶托与框架连接处)出现最小疲劳寿命。整体来说，其Y方向疲劳寿命最小，为145.6 h，但是均满足GB/T 26 9907.4.3中的标准。由此可见瓶托与框架连接处为储氢系统框架中最薄弱的位置，建议对框架中该类结构进行加强优化，该方法也为车载储氢系统框架的设计开发提供指导。
Abstract：The on-board hydrogen storage system should not only ensure the efficient utilization of hydrogen gas during use, but also ensure the safety of relevant vibrations during vehicle operation. Using ABAQUS software to conduct random vibration modal analysis on hydrogen storage systems using a random response analysis method. Based on modal analysis and frequency response analysis,the external support frame of the hydrogen storage cylinder group is taken as the research object of random vibration fatigue analysis. A fatigue life calculation method based on random vibration is proposed through Fe-safe software, and the random vibration fatigue life performance of a hydrogen storage system frame for a certain vehicle is analyzed. The random fatigue life results of the hydrogen storage system framework in the X(left and right), Y(up and down),and Z(front and rear) directions were obtained. Indicating that fatigue failure will not occur in the X direction,and the minimum fatigue life will occur at the same position in the Z and Y directions(at the connection between the bottle holder and the frame). Overall, its Y-direction fatigue life is the smallest, at 145.6 hours, but it meets the standards in GB/T 26 990 7.4.3. It can be seen that the connection between the bottle holder and the frame is the weakest point in the hydrogen storage system framework. It is recommended to strengthen and optimize this type of structure in the framework. This method also provides guidance for the design and development of vehicle mounted hydrogen storage system frameworks.
