  5. 10. Vibrations of partly supported concrete railway sleeper

    University essay from Hållfasthetslära

    Author : Ehsan Rezaei; [2010]
    Keywords : ;

    Abstract : Analytical and finite element solutions to the problem of a vibrating beam on an elastic foundation are presented. An application example is a concrete railway sleeper embedded in an elastic medium (the ballast). The sleeper is also elastically connected to the rails. Eigenfrequencies are calculated and vibration modes are discussed. READ MORE
