摘要 针对仿真模型确认中存在的多元和动态响应问题,提出了一种基于多分辨分析的MEARTH方法,并设计了一种基于贝叶斯决策理论的分类器来综合考虑不同响应的模型确认结果,从而可对多元动态系统的仿真模型的有效性做出综合评估。通过对某汽车乘员约束系统进行模型确认表明,利用所提出方法得到的评分比传统MEARTH方法的评分更稳定,可对多元动态系统仿真模型的有效性做出合理评判。 For multivariate and dynamic response in the simulation model validation, a muhiresolution analysis- based MEARTH method was proposed, and a classifier based on Bayesian decision theory was designed to consider the validation result of different responses synthetically, thus make a comprehensive evaluation to validity of simulation system of the multivariate dynamic system. The model validation of a vehicle occupant restraint system showed that, rating made by the proposed method is more stable than that made by MEARTH method, and can make a rational judgment of the validity of the multivariate dynamic simulation system.
