Dynamic analysis of three-axle semi-trailer road tank driving over barrier

Abstract

This article deals with dynamic analyses of a truck with semi-trailer three-axle road tank for transport of the loose materials (i.e.: corn – barley, wheat, rye, oats, etc.). These articulated vehicles are going over barriers. Calculated forces and reactions of these vehicles are used for the quasi-static analysis of strain and deformation of the road tank. These analyses represent a theoretical preparation of the experimental verification of the road tank. The results of the quasi-static calculation help to define suitable places for strain gauges and accelerometers. Some results of the dynamic simulations will be used for extensive dynamic and fatigue analyses of the road tank and its behaviour in real traffic conditions. Both the dynamic simulations of the simplified truck-tank model and calculation of the separated tank strain-deformation are solved by SolidWorks SIMULATION 2012 [7] which is performed by the finite element method (FEM).
