摘要

安全气囊烟火气体发生器在汽车被动安全系统中占有关键地位,其重要性不亚于其他部件。尽管安全气囊种类繁多,但由于经济型汽车在国内市场的领先地位,国内汽车制造商最感兴趣的是用于驾驶员和乘客安全气囊的单级烟火气体发生器。对于安全气囊气体发生器的专有设计、开发和生产,需要化学工业专家和一般工程专家的共同努力。同时,不应忘记,烟火安全气囊气体发生器的生产受到严格的国家和国际法规的约束。因此,对现代车辆中使用的外国制造商设计的烟火气体发生器进行全面系统分析变得重要和必要,以便为设计和开发专有商业气体发生器以及在俄罗斯联邦境内实现这种装置的大规模生产的整个周期本地化奠定科学和技术基础。给出了气囊气体发生器的一般分类,考虑了单级气囊响应的圆顶型固体燃料气体发生器主要部件的产品设计和生产工艺的关键特点,并以不同世代的气体发生器为例,分析了其装配工艺和基本装配操作的工艺方案。研究结果引起了汽车行业专家的兴趣

Design and Production Technology Features of the Domed Solid Fuel Gas Generators with Single-Stage Response of the Vehicle Passive Safety System
Airbag pyrotechnic gas generators occupy a key position in the vehicle passive safety system with all the importance of the other components. Despite the abundance of various types of the airbags, single-stage pyrotechnic gas generators for the driver and passenger airbags are most interesting to the domestic vehicles manufacturers due to the budget cars leading positions in the domestic market. For proprietary design, development and production of the airbag gas generators, it is necessary to combine efforts of specialists in the chemical industry and in general engineering. At the same time, it should not be forgotten that production of the pyrotechnic airbag gas generators is subject to strict national and international regulation. Therefore, comprehensive system analysis of the pyrotechnic gas generators design by foreign manufactures used in the modern vehicles becomes important and necessary to form scientific and technical base for design and development of the proprietary commercial gas generators and localizing the full cycle of mass production of such devices in the territory of the Russian Federation. General classification of the airbag gas generators is provided, key features of the product design and production technologies for the main components of the dome-shaped solid fuel gas generator with a single-stage airbag response are considered, and technological schemes of the assembly processes and basic assembly operations are analyzed using the example of gas generators of different generations. Results of the study are of interest to the automotive industry specialists
