Structural analysis for floor structure of Rolling Stock

철도차량 바닥 구조 해석

The noise and vibration which are occurred by equipment and rail under the train are directly delivered to passenger and effect on comfort. For this reason, Floating floor structure has been applied to Rolling Sotck for minimizing the noise and vibration. And in respect of Floating floor, the strength is an important design element. Because the train has many heavy equipments and accommodates lots of passenger. At the early design stage of Floating floor, different joint type and thickness of plywood, etc. were applied and some problem happened. To solve the problems and apply to the future projects, the standard model of Floating floor structure was required. To find optimum design and standard model for Floating floor structure of Rolling Stock, the applied Floating floor models were analysed by CAE (computer-aided engineering).
