Dynamic Analysis of Behavior of Three-axle Semi-trailer Road Tank Going on Special Waved Roadway

Abstract

This paper deals with the dynamic analysis of a truck with semi-trailer three-axle road tank for transport of loose materials like corn (barley, wheat, rye, oats, etc.). Firstly, the natural frequencies and mode shapes of truck-tank combination are calculated. Computer simulations of going on special waved road are performed for several speeds. Responses and maximum displacements are analyzed in vertical and lateral directions. These analyses represent a theoretical preparation of the experimental testing of the road tank. Obtained forces and reactions of these simulations may be used for the quasi-static analysis of deformation and stresses of the road tank. These results may also be used for extensive dynamic and fatigue analyses of the road tank and its behavior in real traffic conditions. Dynamic simulations of the simplified truck-tank model are carried out using software SIMULATION 2012 which is based on the finite element method (FEM).
