THE STRAIN-STRESS STATE INVESTIGATION OF STRUCTURAL UNITS OF THE BALLAST PRISM BY TYPE SP3-5/UA

Abstract

In the article the results of analytical and experimental studies of the stressed-and-strained state of load-bearing elements of structure of ballast prism planner of SPZ-5/UA are presented. The analytical research is performed using the finite element method (FEM). Its results are used during realization of performance dynamic tests on durability. On the basis of analysis of the calculation and experimental data obtained the estimation of durability of construction of ballast prism planner SPZ-5/UA under the action of loads corresponding to the different operating modes is executed.
