摘要
为探究腿型碰撞器标定试验的工作原理,详细对比了先进行人腿型碰撞器(aPLI)与柔性腿型碰撞器(FlexPLI)在结构上的差异,总结了腿型碰撞器动态标定和静态标定限值确定的方法分别为混合组群均值估计法和三点弯曲挠度试验法,归纳并比较了2种腿型碰撞器在动、静态标定限值上存在的显著差异,在此基础上剖析了这些差异的内在原因,动态标定限值差异的主要原因是aPLI增加了模拟人体上肢的质量模块,静态标定限值差异的主要原因是aPLI腿部和膝部结构改变。
In order to explore the working principle of legform impactor calibration test,this paper compared in detail the structural differences between advanced Pedestrian Legform Impactor(aPLI)and Flexible Pedestrian Legform Impactor(FlexPLI),summarized the methods for determining of dynamic calibration limits and static calibration limits of legform impactor as the mixed group mean estimation method and the three-point bending deflection test method respectively.The paper also summarized and compared the significant differences between dynamic calibration limits and static calibration limits of the two types of legform impactor,and analyzed the immanent cause for these differences.The main cause for the difference in dynamic calibration limits was the addition of mass module to simulate human upper limbs in aPLI,while the main cause for the difference in static calibration limit was the structural changes in the leg structure and knee structure of aPLI.
