SAE J3121_202202《氢燃料汽车碰撞试验实验室安全指南》标准解析

摘要：

近年来，氢能行业不断发展。氢燃料汽车与传统内燃机汽车具有一些相同的安全特征需求，车辆需要符合厂家及政府监管的相关标准要求，而由于氢燃料汽车内部包含高压气体、高压部件等危险源，在进行碰撞等破坏性试验时具有较高的安全要求，因此SAE在2022年2月份发布了SAE J3121_202202《氢燃料汽车碰撞试验实验室安全指南》，旨在告知碰撞测试、设施管理等相关人员安全风险点及对应措施。本文主要解析SAE J3121中相关技术要求，为氢燃料汽车碰撞试验提供试验流程、安全管理等相关指南方法。

Abstract:

In recent years, with the continuous development of the hydrogen industry, the number of hydrogen vehicles has increased significantly. Hydrogen vehicles have some of the same safety characteristics as traditional internal combustion engine vehicles, and the vehicles need to meet the relevant standards and requirements of manufacturers and government supervision. Because hydrogen vehicles contain high-pressure gas, high-pressure components and other dangerous sources, they have higher safety requirements when conducting destructive tests such as collisions. SAE issued SAE J3121_202202, Hydrogen Vehicle Crash Test Lab Safety Guidelines, in February 2022 with the purpose to inform relevant personnel of collision test, facility management and others of the safety risk points and corresponding measures. This paper mainly analyzes the relevant technical requirements in SAE J3121, and provides the test process, safety management and other relevant guidance methods for the hydrogen vehicle crash test.
