The Reasons for Hybrid Light Pole Failures – An Analytical Study

This paper presents the results of a durability analysis of a hybrid light pole. The developed model includes a supporting structure of a pole with photovoltaic panels, a wind turbine and a boom with a light case. Due to various operating conditions, these poles may be characterised by a different configuration of the mutual spatial distribution of individual components. This results in a large diversity in the analysis results, hence the fact that the research was performed for the selected configuration variant for which the most unfavourable operating conditions were forecasted. In order to reveal potential stress concentration areas, a series of structural analyses was applied using the finite element method. As part of the work, changes to the supporting structure of the pole were proposed and to confirm the possibility of improving the resistance of the structure, additional analyses were conducted.
