Application of the Uncertainty Evaluation Algorithm to Automobile Accident RecurrenceDENG Hai-ying, MO Yao-zu, JIANG shu-xia, HAN Zhi-gang School of Industry Technology, Central South University of Forestry and Technology, Changsha 410004, Hunan, ChinaAbstract:This paper introduces the uncertainty theory and its evaluation algorithm, and puts forward the vehicle-velocity calculating formula based on energy conservation and the characteristics in vehicle-impacts. The standard uncertainty of each equivalent velocity is respectively evaluated by selecting a suitable factor in a vehicle-impact. Taking the accumulation and spreading of the uncertainties into consideration, the paper obtains the results of combined standard uncertainty and stretch uncertainty of the vehicle-velocity. They can be used to check the credibility of the accident reconstruction. The practicability of the method is proved through analysis- calculating and computer testing of a specific example.[著者文摘]
