Popis: | 96 This paper aims to understand the performance of the driver air airbag (DAB) through static experimental analysis under different circumstances, which include the high-temperature (80 °C) and low temperature (-30 °C) environments. The requirement of the DAB is that the DAB has to deploy completely within a specified time period under both temperature environments. The results of the experiments show that under the high temperature environment, the DAB shows a compete deployment filled with enough pressure. The higher the temperature, the better performance of the DAB. However, under the low temperature environment, the DAB is unable to meet the test requirement. In order to further understand the reason of the low-temperature failure, the effect of inflator on the experimental results has also been investigated by measuring its pressure-time curve during the experiment. The results show that the failure under the low temperature environment may be due to the physical characteristics of the DAB rather than the possibility of inferior quality of the inflator parts. In order for the driver to receive adequate protection under low temperature circumstances, it is suggested that the DAB should be equipped with a special seat belt to meet the requirement. The future direction of the development of the DAB is to design a new gas generator to meet the low-temperature requirements. |
