摘要
为研究侧面柱碰及侧面可变形壁障碰撞试验特点,选取某B级轿车分别进行了Euro-NCAP中侧面柱碰试验和C-NCAP侧面可变形壁障(AE-MDB)试验。分析了车身加速度以及假人伤害特点,结果表明:侧面柱碰撞相比可变形壁障碰撞对乘员有更大的损伤风险,车身加速度更大,车身侵入量更大、局部变形更严重。为减少侧面碰撞伤害,需要增加碰撞侧车身局部强度,避免小区域重叠刚性碰撞。
In order to study the characteristics of side pole impact and side deformable barrier impact test,a B-class car is selected to carry out the side pole impact test in Euro-NCAP and side deformable barrier(AE-MDB)test in C-NCAP.The characteristics of body acceleration and dummy injury are analyzed.The results show that compared with the deformable barrier collision,the side pole collision has a greater risk of injury to passengers for vehicle body acceleration,at the same time,the intrusion is greater and local deformation is more serious.In order to reduce the side impact damage,it is necessary to increase the local strength of the body at the side of collision to avoid small area overlapping rigid collision.
