Transverse Oscillation of a Base Slab Section of Ballastless Track
World of Transport and Transportation, 2019 The study is devoted to construction of a mathematical model of a slab of a ballastless base of a railway track, assembled from separate segments fastened together. Each rectangular segment is modeled by a transversely isotropic prestressed plate. An equation has been obtained that allows researchers to study the natural oscillation frequencies of a ...
