摘　　要：为了探究正面碰撞减速度波形参数对假人胸部损伤的影响,采用将减速度波形等效为双线性近似等效波形(BSAW)的方法,利用MADYMO完成正面碰撞仿真。结果表明,在保证车体速度和变形量不变,BSAW曲线在第一阶段斜率较大、末尾峰值较高时所对应的假人损伤较小;在仅保证速度变化相同的情况下,BSAW参数对于胸部X向减速度峰值的影响显著性由大到小依次为一阶段峰值、二阶段峰值、一阶段峰值时刻。In order to investigate the effect of frontal collision deceleration waveform parameters on dummy chest injury,the method of equating the deceleration waveform to a Bi-Slope Approximation Wave(BSAW)was used to complete the frontal collision simulation using MADYMO.The results show that the dummy damage corresponding to the bilinear deceleration waveform curve with a larger slope in the first stage and a higher peak at the end is smaller under the condition that the vehicle speed and deformation are guaranteed to be constant;the influence of BSAW parameters on the chest deceleration peak along the X-direction is from the first stage peak,the second stage peak,and the first stage peak moment in decreasing order under the condition that speed change remains unchanged.
