Analysis and Application of the Tire Blowout Model Based on Fault Tree

Tire blowout is one of the main factors leading to a fatal traffic accident. Finding out and monitoring the main factors that affect tire safety performance is an important way of reducing traffic accidents caused by tire blowout. Based on the fault tree analysis of safety system engineering, the fault tree model of tire blowout was established; the structure importance coefficient of each basic event was computed; the abnormal vehicle states of the main factors arousing tire blowout were found out and sorted by the structure importance coefficient as follows: over-speed, under-inflation pressure, overload, eccentric load, over-inflation pressure, etc. The vehicle monitoring and early warning system was developed based on the above-mentioned analysis result, which realized real-time monitoring of factors affecting tire safety performance and reduced the probability of tire blowout. This system was of great significance to the prevention of tire blowout.
