Numerical and experimental analyses of non-energy absorbing lighting poles
Journal Title: Archives of Mechanical Technology and Materials - Year 2018, Vol 38, Issue
Abstract
Apart from the strength requirements, modern lighting pole designs have to meet a number of safety requirements in the event of collisions. The paper compares the experimental tests performed at the collision test track according to EN 12767 with the results of the numerical analysis carried out in Ansys LS-DYNA. The objective of the work is to prepare a new structure of a thin-walled lighting pole of steel which minimizes absorption of the kinetic energy of the vehicle and, simultaneously, its production costs are comparable to those of a standard pole. The tests were carried out at an impact speed of 100 km/h.
