一种安全气囊展开的试验系统 技术领域
本发明属于汽车零部件试验技术领域，特别是涉及一种安全气囊展开的试验系统。
背景技术
安全气囊能够在汽车出现碰撞事故后几十毫秒内完成工作，可以快速产生含有一定量的气体的安全气囊，以减轻司乘人员的伤害程度，避免司乘人员发生二次碰撞。
安全气囊主要分布在车内前方和侧方，正驾驶位和副驾驶位的正气囊可以在正面碰撞发生的瞬间有效地保护驾驶员和副驾驶位乘员的头部、胸部以及膝部，侧气囊可以在侧面碰撞发生的瞬间有效的保护车内人员的上肢、胸部、胯部和头部。因此，安全气囊的质量直接决定着司乘人员的安全。
然而，现有技术中的安全气囊在其使用的展开过程中会发生剧烈晃动，因此存在以下问题：
由于缺乏对安全气囊的展开过程进行定期的抽检，安全气囊在使用过程中，当安全气囊迸射出的药剂在老化和吸湿后，用户不能及时检测到药剂的性状变化数据，因此在使用过程中安全气囊极易发生爆炸事故。
由于安全气囊的工作时间非常短(几十毫秒)，且压力比较高，因此有必要研发一种能够检测安全气囊展开的速率、姿态、形貌以及金属迸射物性状数据的安全气囊展开的试验系统，以尽可能地降低安全气囊发生爆炸事故的概率。

首先，打开DAB-1型安全气囊展开的试验系统的电源，控制系统控制高速摄影仪和高亮LED灯开启以进行预热；开启安全联锁系统，此时点火系统处于短路状态，警示灯为绿色，将DAB-1型安全气囊装入试验台的卡盘中，确定安全气囊安装无误后连接点火系统的点火线路，该点火线路是点火系统的一部分并位于在安全气囊旁边，点火线路和插头相连， 试验进行时直接插上该插头。
操作人员撤离试验室，关闭安全门，安全联锁系统判断实验室无人并且安全门处于关闭状态时，安全联锁系统发送信号给控制系统，以控制开启点火系统；
然后，控制系统控制点火系统启动，点火系统自动对DAB-1型安全气囊点火系统的电阻等参数进行检测，确认该安全气囊点火系统的电阻等参数为预设的电阻等参数，控制系统调整高速摄影仪和高亮LED灯的角度，满足试验要求后，按下试验台上的试验按钮，两台高速摄影仪通过垂直90度两个方向自动将DAB-1型安全气囊展开过程的速度、姿态、形貌和迸射物等安全气囊的展开数据进行记录并存储，并将获得的安全气囊的展开数据发送至外部计算机设备；
最后，外部计算机设备根据安全气囊的展开数据生成分析报告。
本实施例中的安全气囊展开的试验系统可以用于为安全气囊的研制、生产等设计和鉴定输入参数。
具体的，根据安全气囊展开的半径和时间得到安全气囊展开的速度，即以安全气囊展开的半径来表示展开的百分比，该百分比与安全气囊展开的时间之间的比值即是安全气囊展开的速度；
根据安全气囊的展开的水平面积与预设的标准圆的面积的比值获得安全气囊的展开圆度，利用该展开圆度的数值表示安全气囊的姿态；
所述安全气囊的形貌包括安全气囊的长度、宽度、形状等数据；其中，安全气囊的迸射物主要包括安全气囊中少量的防护用金属屑。
本发明的有益效果为：
(1)本发明安全气囊展开的试验系统可以对安全气囊展开过程的速率、姿态、形貌以及是否有金属迸射物等进行试验和鉴定，可以为安全气囊的试验研究设计、出厂检验和司法鉴定等提供数据。
(2)本发明安全气囊展开的试验系统具有监测安全气囊点火系统功能性和安全性的优点，并对结果进行显示和报警。
(3)本发明安全气囊展开的试验系统具有安全联锁系统，在试验过程中如遇到人员误操作、试验安全门未正常关闭、人员未撤离等情况，系统会自动锁死，从而确保整个试验的安全。
(4)本发明安全气囊展开的试验系统中采用的LED灯、高速摄影仪等具有自动调节 功能，大大提高工作效率。
(5)本发明安全气囊展开的试验系统中的烟雾除尘装置与试验系统联动，当试验过程中产生烟雾时，烟雾除尘系统会自动开启，将试验过程中的烟雾排出试验室。
(6)本发明安全气囊展开的试验系统具有体积小、移动方便、人机交互合理等优点。
