摘要
为探究欧洲新车评价程序(Euro NCAP)移动渐进变形壁障(MPDB)碰撞工况中驾驶员右侧小腿伤害超标的主要原因,对假人腿部伤害评价方法进行解析,通过测试结果分析得到造成驾驶员小腿伤害超标的主要原因是腿部受到的弯曲力矩过大。研究腿部伤害机理并对受力过程进行分析,将车辆加速踏板变形量与腿部伤害指标进行关联,结果表明,脚部受到的冲击受加速踏板变形量影响,将导致小腿受到的弯曲力矩过大。
In order to explore the main cause for exceeding the limit of driver’s right calf injury in European New Car Assessment Program(Euro NCAP)Mobile Progressive Deformable Barrier(MPDB)collision conditions,the driver’s right leg was analyzed by the dummy’s leg injury evaluation method.Through analysis of the test results,it is concluded that the excessive bending moment on the leg is the main cause of exceeding the limit of driver’s calf injury.The mechanism of calf injury and stress process were analyzed,and the pedal displacement was associated with the leg injury index.The results show that the impact of the foot is affected by the deformation of the accelerator pedal,resulting in excessive bending moment of the calf.
