Review on Airtight Fatigue Strength Research of the New Generation High-Speed Train

Abstract:

Structure failure risk caused by air wave on high-speed vehicle airtight body is considered and it’s necessary to bring out the conception of airtight fatigue strength and start related research. There is a review of airwave and structure fields, including air dynamic of rail-vehicle, load carrying structure and strength test standard. Nowadays, the direction of air dynamic research is focused on how to reduce air wave pressure and enhance stability of running vehicle; the structure study is focused on static and transient load carrying response of wheels, bogie and so on structures under traction running and weight load. It’s not been fully researched that how the airtight structure vehicles response when carrying air-dynamic in long run. Based on current research, an analysis line is brought out which contains simulation and experiment, fluid-structure interaction study and structure fatigue assessment calculation
