Numerical and experimental diagnostics of the behaviour of the palette-pack machine

Abstract

The subject of the present investigation is determination of the behaviour for the cement palette-pack machine in F.C. Beočin. As we wanted to define the reason of the failure of the construction which was in non-stationary impulsive regime of work, it was necessary to analyse the problem using both numericaland experimental approach. The numerical calculation was done using finite element method, specifically program package KOMIPS (T. Maneski). On several places on the construction the gauges were established and appropriate dynamic stresses were measured to verify the numerical results. The failure strength of the material was checked in laboratory on the tensile specimen. A comparative analysis of the obtained results and appropriate calibration was done, and the reason for the failure of the construction was determined. A necessary reconstruction was performed.
