The foundation model is based on Winkler hypothesis. Various methods are described for treating the analysis of beams on elastic foundation subjected to point load in transverse direction. An example problem is solved using finite element package ANSYS. Keywords: Beam on Winkler foundation, dynamic analysis, moving loads, fem formulation I. INTRODUCTION The need for the study arose while analyzing the conveyor galleries supported on trestles in coal power plants. Earlier research suggests that these galleries can be treated as beams on elastic foundation. Beams on elastic foundation is treated by engineers and researchers before but it is not discussed in this context. This paper details the methods to analyze such beams subjected to various load cases. Roland Jančo[1] described numerical methods for solution of beams and frames on elastic foundation subjected to static load. He suggests that elastic foundation can be approximated by springs of equal stiffness. His work is reviewed in this paper for a
