为研究正面偏置碰撞中驾驶员侧安全气囊(DAB)的吸能作用，在10款车型的正面碰撞试验中，测量假人颈部约束力、头部加速度，计算出气囊作用下头部加速度、头部降速和气囊吸收能量。试验结果表明：在气囊作用下，在假人头部伤害允许指标(HIC)低于高性能限值情况下，假人头部平均降速为22 m/s，假人头部x向是主要吸能方向，气囊平均吸收动能为1.1 kJ，占总吸收能量的80%以上；x向吸收能量越高，对颈部保护效果越好。安全气囊的开发应以此为目标。因而，提高气囊在假人头部x向吸能作用，可直接提高气囊刚度，也可通过调整安全带约束强度来实现。

Frontal offset impacts were tested for 10 vehicles to investigate driver airbag (DAB) absorption energy effect. In the tests, the neck loads and the head accelerations of a dummy were measured to work out the head accelerations, the head dropped velocities, and the airbag absorption energy under airbag effect. The test results show that the average head dropped velocity is about 22 m/s, the head x direction is the main absorption energy direction, the average absorption energy is about 1.1 kJ which is about 80%of the overal absorption energy under the circumstances of the airbag effect with the dummy Head Injury Criterions (HICs) being below high performance limit value. The protection neck effect is the better when x direction absorption energy is higher which should be an aim to develop an airbag. Therefore, heightening the airbag absorption energy effect in dummy head x direction may directly heighten the airbag rigidity or adjusting the seatbelt restraint intensity.
