摘要：

微型客车与运动型多用途汽车(SUV) 之间发生侧面碰撞时，导致被撞车车内的乘员伤亡率很
大，兼容性突出。本文以某微型客车和SUV 为例，采用仿真研究方法，发现SUV 与目标车微型客车
之间的侧面碰撞兼容性不理想。然后利用单一变量控制原理，分别改变两车质量比、目标车侧围刚
度以及几何结构，进行了多组仿真分析，以研究侧面碰撞兼容性的影响因素。结果表明：两车质量比
对B 柱腰线处的最大侵入速度的影响最大，侧围刚度对B 柱侵入量的影响最大，几何结构对目标车
车门最大侵入量的影响最大。

Abstract:

The side crash accident between SUV (sport utility vehicle) and minivan leads to serious injury
for passengers in the impacted car. The authors explored the compatibility between minivan and a SUV
using simulation method. The compatibility between minivan and SUV was undesirability as found in premier
simulation. Single variable principle was used to explore influence factors for side impact compatibility. And
multi-group simulated analyses were carried out by changing the mass ratio between two vehicles, the lateral
stiffness of target vehicle, and the geometric structure, respectively. The results show that the two-vehicle mass
ratio has the most effect on the B pillar maximum intrusion velocity at waist line; the side stiffness has the most
influence on the B pillar intrusion displacement; and the geometric structure has the most impact on the target
vehicle door maximum intrusion displacement.
