Strength analysis of the freight wagon for the transport of petroleum products with a sliding bolted connection

Abstract

his paper presents the strength analysis of the wagon for the transport of petroleum products with a sliding bolted connection according to TSI standard and norm EN 12663: 2010 standard. In order to optimize the number of elements of the FEA model and its complexity, the authors had a task to analyse the influence of bolted connections, which would completely correspond to the real connections. The primary objective of the analysis was to show a good agreement of the stress values obtained by FEM analysis with stress values obtained by strain gauges placed on a wagon prototype. According to comparative analysis of obtained and measured stress values, it has been concluded that the bolted connections modelled in the manner shown in this paper really transfer loads to other parts of the wagon construction and can be used to analyse complex structures exposed to different types of loads
