| 摘 要： | 本文是数据挖掘方法在乘员约束系统FE(Finite Element)数据及其碰撞仿真结果数据上的应用。针对CAE数据的特点，基于面向对象思想对乘员约束系统数据进行数据挖掘前的数据准备。应用属性选择、决策树分类算法对98例碰撞仿真实验数据进行挖掘，得到乘员约束系统关键参数与乘员伤害WIC值的关系，并应用交叉验证方法对所得决策树进行了评估。通过实例验证，所得知识符合实际、对乘员约束系统的设计具有一定参考价值，是对海量CAE仿真数据进行知识发现的成功尝试。

| Abstract: | The applicability of data mining on the finite element data and the crashworthiness simulation data of occupant restraint system was demonstrated.According to the characteristics of CAE data,a framework for data preparation was developed based on object-oriented ideology.Decision tree and attribute selection algorithms were used to perform data mining on the crash simulation data of 98 instances.The results of the data mining give us a deeper insight into the interrelations between the key parameters of occ... |
