为了再现交通事故 ,该文从间接描述碰撞阶段的特征参数出发 ,采用不同的参数子集 ,建立了分类碰撞模型。提出了虚拟模型的概念 ,应用人工智能技术 ,根据特定碰撞类型的特点进行分析 ,充分利用这些特点进行模型假设 ,简化了模型的求解。编制了计算机应用软件。并用日本汽车研究所与整车碰撞实验数据系列进行验证 ,结果表明本模型可以应用于事故再现 In order to reconstruct the traffic accident, this paper sets out the classification collision model by indirectly describing the characteristic parameters of the collision stage and using different parameter subsets. The concept of virtual model is put forward. The artificial intelligence technology is applied to analyze the characteristics of a specific collision type. The model assumptions are fully utilized to simplify the model. Compiled computer applications. And verified with the Japan Automobile Research Institute and the series of vehicle collision test data, the results show that this model can be applied to accident reproduction
