摘要: 欧洲的研究项目SENIORS提出新型行人下肢模型FlexPLIUBM,日本汽车研究所和日本汽车制造商协会提出新型行人下肢模型aPLI,这两种下肢模型均具有较好的生物力学响应,包括运动响应和力响应。本文中针对目前应用中的下肢模型FlexPLI和未来可能会应用的上述两种新型下肢模型进行了一系列基础分析。首先对下肢模型FlexPLI、FlexPLIUBM和aPLI的总质量、分段质量、质心位置、结构、刚度和尺寸等关键参数进行了剖析和对比;然后基于关键参数,对其碰撞过程进行了运动学和力学分析,得出评价指标之间的区别和规律;最后通过试验对分析结论进行了验证。上述关于行人下肢模型FlexPLI、FlexPLIUBM和aPLI的对比分析和验证结论,可为车辆前保险杠的开发提供指导。

Abstract: European project SENIORS proposed a novel pedestrian lower limb model FlexPLIUBM, and JARI and JAMA in Japan proposed model aPLI. These two models show better biomechanical responses, including motion and force responses.A series of basic analyses are conducted on the currently used model FlexPLI and the above-mentioned two models, which may be applied in the future, in this paper. Firstly, some key parameters, including total mass, segment mass, position of mass center, structure, stiffness and dimension of lower limb models FlexPLI, FlexPLIUBM and aPLI are analyzed and compared. Then based on these key parameters, kinematics and mechanics analyses on crash process are carried out with the rules of and differences between evaluation indicators obtained. Finally, tests are performed to verify analyzed conclusions.All the comparative analyses and conclusions on pedestrian lower limb models FlexPLI, FlexPLIUBM and aPLI can provide guidance for the development of vehicle front bumper.
