A New Method for Solving the Problem of Determining the Characteristics of Spatial Stiffness and Elasticity of the Rail Threads and Stresses and Strains in Rails

The reference data given in technical literature on the characteristics of spatial stiffness and elasticity rail threads conditions joint action rails vertical horizontal lateral forces torsion are very different some cases contradictory. This situation is due to lack an accurate analytical solution this problem provision for materials only experimental research data, which clearly different, not railway structures, but also significantly differ acting external (P, H, Mtor). purpose article present a new method determining computation stresses strains that occur them, under complex dynamic (Pdyn, Hdyn) simultaneously with torque moment Mtor arising from off-center applied wheel loads. solving was used paper. It includes theoretical part results experiment. Using researches head sole at constructions modern fastenings measured. second task determination real values modulus thread bends conjunction its simultaneous solved by methods. As author’s were obtained torsion. These track constrictions (R65, R50, UIC60) concrete wooden sleepers unlined or lined types (KB, KPP-5, KPP-1, D0). And these functional dependence ratio P/H.
