Smart Sensors for Monitoring of Fatigue Damage and Exhaustion of Exploitation Resource in Intelligent Transportation Systems 2001-01-3178

To the moment the desire to decrease a weight of constructions was a very hard challenge and interesting task for specialists in aerospace engineering. As a result, the problem of fatigue and other deformation damages became quite important and diagnostic methods were very intensively developed. At the same time automotive professionals provoke and face the same problems during development of advanced vehicles with decreased mass. Abrupt exhaustion of exploitation resource of crucial elements of transportation systems can lead to their unstable or uncontrollable behavior, and destruction. It is especially dangerous for the modern and future transportation systems under conditions of high-velocity and intensive traffic. Finally, it can lead to safety risk and catastrophic consequences even.
That is why for monitoring of fatigue damage and exhaustion of exploitation resource in intelligent transportation systems we propose to apply smart sensor technology that was developed by us for inspection of fatigue damage in aviation constructions during last years [1, 2 and 3]. This technology is based on sensor surface scanning, capturing information about surface evolution on many scales, processing this information and deriving conclusions as to the level of the correspondent exhaustion of exploitation resource.
