远端乘员保护虚拟测试中数据相关性评估方法研究

Study on Correlation Evaluation Method for Virtual Test Based on Far Side Occupant Protection

为研究不同的数据相关性评估方法在远端乘员保护虚拟测试中的适用性,首先通过分析2个车型的远端碰撞工况基础数据,确定了11个动态响应量,进一步应用相关分析(CORA)和ISO/TS 18571方法进行相关性评估,采用误差分析法对相关性评估结果中差异较大的响应量进行分析,证明了ISO/TS 18571方法相比CORA方法所得到的评价结果更加合理。

To study the applicability of different data correlation evaluation methods for virtual evaluation of far side occupant protection condition,firstly,the dynamic response of 11 simulation and test data was determined by analyzing far side occupant basic data of two vehicle models,CORrelation and Analysis(CORA)and ISO/TS 18571 methods were further applied for correlation evaluation,and error analysis method was used to analyze the response with significant differences in the correlation evaluation results,and it is concluded that ISO/TS 18571 method provides more reasonable validation results than CORA method.
