[Abstract]:Among the many traffic accidents, the frequency of automobile traffic accidents is the highest, which seriously threatens the human security. With the rapid growth of the national economy and the improvement of people's living standards, cars have been more and more popular in ordinary families. Automobile has become the most popular means of transportation in people's life. With the popularity of automobiles, people's awareness of automobile safety is constantly increasing. It is necessary to raise new requirements for the safety of vehicles, which can reduce casualties and economic losses in automobile traffic accidents. Reducing casualties in Automobile Traffic Accidents to the maximum extent is an important subject to be solved in the Field of vehicle passive Safety. Passenger restraint system is an important research content in the field of vehicle passive safety. The ratio of airbag in passenger vehicle is higher and higher. How to coordinate airbag with seat belt and other safety parts is very good match with body. It is difficult to optimize the airbag system to achieve the optimal protection effect to the occupant. This paper introduces the development and design process and experimental research of the double airbag in front row of a passenger car in detail, combined with the development process of the airbag. The air bag development of passenger vehicle is mainly divided into two main lines: parts development and system development parts development take full account of platformization, reduce the cost of parts and reduce the development cycle, In the case of realizing the maximum profit of the company and adopting the platform structure, the volume of the air bag is basically determined by the gas generator. The emphasis of development lies in the development of air bag cover (injection mould) and the design of the connecting structure of environmental parts. The airbag modules need to meet the requirements of the host machine in order to match the environmental components. After the performance experiment (including design and verification experiment and production verification experiment) is qualified, it can be approved by PPAP of main engine factory, and the development of airbag system in mass production condition is mainly divided into simulation stage, data acquisition stage, slide platform optimization stage, and vehicle verification stage. Through the whole process, the initial air bag parameters can be obtained in the calibration simulation stage of airbag ECU, which can be used in the initial sliding platform optimization experiment, and the sliding platform optimization experiment and simulation interactive. Finally, the data collection of airbag parameters satisfying the development goal of the whole vehicle is obtained, and the acceleration data of position acceleration of ECU (airbag controller) and the acceleration data of seat belt pressure sensor are obtained, such as the acceleration data of B column and the data of seat belt pressure sensor. After determining the impact ignition time of airbag ECU under the regulation speed, after determining the final air bag parameters in the slide platform optimization experiment, the airbag module installed with this parameter and the airbag ECU were used to carry out the actual vehicle verification experiment. Finally, the body data obtained from this experiment is compared with the data from the data collection stage, and the calibration adjustment of the airbag ECU is carried out, and the final parameters of the airbag ECU are determined, and the final parameters of the airbag ECU are determined. The final parameters of the airbag ECU are confirmed by the main engine factory PPAP. Mass production state
