Introduction

The repair and reconstruction of belt wagons and stackers are performed by applying a developed methodology of structural strength diagnostics. It includes procedure by computer calculation using the finite elements method and experimental tests. Finding and solving the cause of problems requires use of numerical and experimental diagnostics of element strength, computer modelling and calculation of loaded structures (KOMIPS) using numerical finite element method through static, dynamic, and thermal analysis. The purpose of experimental tests is to measure the loads in service, deflections, displacements, stresses, and acceleration. In other words, it defines necessary input for the calculation and also verifies the results. This calculation procedure minimizes the scope of experimental tests.
