Natural Frequencies of Railway Slab on Winkler Foundation

摘要

Natural frequencies and natural modes represent the basic dynamic characteristics of all dynamic systems. They define the dynamic individuality of dynamic system. It is useful to know approximate relations giving the results with adequate accuracy. The analysis of plates in contact with elastic foundation is the part of structural dynamic which demands hard numerical solutions. The submitted paper presents approximate relations enabling with satisfactory accuracy to carry out the assessment of natural frequencies of the slabs on elastic foundation at variable subgrade stiffness.
