Study on vehicle fire safety: Statistic, investigation methods and experimental analysis

摘要

Vehicle fire is a very serious safety accident. At the same time, the defects of vehicle products are closely related to vehicle fire accidents. Based on the comprehensive analysis of the defects of vehicle product recall data and the cause of vehicle fire accidents, this essay explicitly points out that the defects of fuel system, electrical system and other flammable liquid transportation systems are the main causes of vehicle fire, and take the detectability as index to reveal the correlation between detectability and the tendency of accident occurrence was negative. Based on scene investigation and experimental analysis, a method for in-depth investigation of deep accident in vehicle fire is proposed, which uses scene reorganization and traces inspection as means. Through the application analysis of three different vehicle fire cases, it is verified that the accident in-depth investigation method can achieve good results in judging whether the vehicle products have defects and the relationship between defects and fire accidents.
