Abstract

To calculate the stress-deformed state of road-tanker metal structures during the liquid cargo transportation, the solution for bending axially and symmetrically loaded circular plates is proposed, which is based on the theory of elasticity approach. Dependencies for calculating stresses and displacements under arbitrary load law and support type are substantiated. Deformation of the support under the action of axisymmetric loading leads to appearance of a temperature field.

Highlights

IntroductionAccording to analysis of operation conditions of vehicles for transporting the liquid cargoes, the dynamic loads and influence of external environment, in particular temperature and precipitation, are the main factors that cause destruction of assembly units (load-bearing systems and tanks of vehicles), their parts (supports of tanks, etc.), as well as connections [1,2,3,4,5,6,7]
Introduction and literature reviewAccording to analysis of operation conditions of vehicles for transporting the liquid cargoes, the dynamic loads and influence of external environment, in particular temperature and precipitation, are the main factors that cause destruction of assembly units, their parts, as well as connections [1,2,3,4,5,6,7]
The exact solution of equations of the theory of elasticity in the closed form for round plates with axisymmetric loading is possible only taking into account the temperature change, which appears at deformation from action of normally added forces

Summary

Introduction

According to analysis of operation conditions of vehicles for transporting the liquid cargoes, the dynamic loads and influence of external environment, in particular temperature and precipitation, are the main factors that cause destruction of assembly units (load-bearing systems and tanks of vehicles), their parts (supports of tanks, etc.), as well as connections [1,2,3,4,5,6,7]. This fact contributes to formation of wet films on surfaces of vehicles, with regard to condition of surfaces: coating, roughness, hardness etc. This fact is stipulated by the random nature of the sources of disturbances (transport modes, inequalities of the road, geometry, etc.)
