摘要： 在行人保护法规中，吸能结构的伤害值指标与关键零部件的板厚、材料等参数高度相关。该文提出了一种
适合于高大运动型多功能车(SUV) 车型的前端行人腿部保护的吸能结构设计方案。该设计方案，结合多款车型的改
进，运用“计算机辅助工程(CAE)”环境下的“试验设计（DOE）”理念，对行人腿部保护分析模型中吸能结构做非线性
的DOE 处理，改变吸能结构中关键零部件的板厚、材料，比较非线性分析结果，并与试验结果进行相关性分析，获
得了预期方案。

Abstract: The conventional theory is not suitable for sports utility vehicle (SUV). A compatible project was designed for SUVs
associating with design improvement items for pedestrian protection of several vehicles. The thicknesses and material parameters
of the key components in energy-absorbing structures are highly sensitive to the injury criterion defined in pedestrian protection
regulations. If associated analysies of deferent parts are not sufficient, thicknesses and materials can then hardly be more
ideal for design projects. Nonlinear analysis was made for pedestrian protection energy-absorbing structures of vehicle models
using design of experiment (DOE), with thickness of some structure strength parts changed and the analysis results compared.
Correlation analysis with test results was also made. The results show that the expected design effects can be obtained.

Key words: pedestrian protection, sports utility vehicle (SUV), energy-absorbing structure, computer aided engineering (CAE), design of experiment (DOE)
