| 目的 为了确保氢能源汽车的使用安全性，研究氢能源汽车在行驶过程中，由路面凹凸不平和无规律性振动对能源供给装置的包装件-供氢系统随机造成的影响。方法 通过Ansys Workbench有限元分析软件，采用模态叠加法，并输入GB/T 4857.23—2012中的功率谱密度激励，对供氢系统进行随机振动分析。结果 获得了在1σ，2σ，3σ下的应力与位移分布，得知最大应力发生在系统鞍座，而最大位移发生在系统框架。结论 证明了氢系统的使用安全性，同时为今后的研究以及更多运输包装系统的PSD随机振动提供了依据和保障。 |

| The work aims to study the random influence of uneven road surface and irregular vibration on the hydrogen supply system (package of the power supply system) when the hydrogen vehicle is driving, in order to ensure the safe use of hydrogen vehicle. Based on Ansys Workbench (finite element analysis software), the random vibration analysis of the hydrogen supply system was carried out by using the modal superposition method and inputting the power spectral density excitation in GB/T 4857.23—2012. The stress and displacement distributions of 1σ, 2σ and 3σ were obtained, the maximum stress occurred in the system saddle, while the maximum displacement occurred in the system frame. It is proven that the hydrogen system can be used safely and provides a basis and guarantee for the future research and PSD random vibration of more transportation packaging systems. |
