摘　　要：气体发生器为气体发生装置,是安全气囊系统的核心部件,气体发生器内部储存的固体燃料,即气体发生剂,在化学反应完成后无法进行二次使用,因此整个测试过程是不可逆的;在前期产品设计及装配环节,可以单独对气体发生器内部储存的固体燃料,即气体发生剂进行单独测试,以达到前期质量及成本控制的目的,一般使用密闭燃烧室试验(Closed Combustion Chamber test)测试方法,采用BPF值作为气体发生剂性能指数的重要参考值。The gas generator is a gas generating device, which is the core component of the air bag system.The solid fuel stored in the gas generator, i.e. the gas generator, can not be used again after the completion of the chemical reaction, so the whole test process is irreversible. In the early product design and assembly, the solid fuel stored in the gas generator, i.e. the gas generator, can be used separately In order to achieve the purpose of quality and cost control in the early stage, the closed combustion chamber test method is generally used, and the BPF value is used as an important reference value for the performance index of gas generator.
