Phone: 01922 453038 www.hyperon-simulation-and-cad-services.co.uk Simulation of AJWSP10033_FOLDED _ST_FR Date: 06 May 2017 Designer: Study name: AJWSP10033_FOLDED_STATIC Analysis type: Static Description The purpose of this analysis is to investigate the structural integrity of a Freestanding Internal Totem, which is intended to provide directional wayfinding and illumination to station concourse areas. There are two configurations for this product, one designed with box section galvanized steel, which is the subject of separate analyses, and the second with folded sheet metal galvanized steel, which is the subject of this static analysis. We not only provide comprehensive study properties, results and conclusions for this analysis, but also provide comparisons between the two static studies, together with those of frequency studies which are also performed for each design, so facilitating further conclusions to be drawn.

Simulation Preparation Considerations For the purposes of this simulation, the following considerations are employed: All loadings are assumed to be static. Global bonding is applied. All unnecessary fasteners, washers, features, parts and subassemblies are excluded from this analysis. Fixed geometry is employed at the base of the design in order to simulate its fixity to the ground. A vertical load of 862.4N is applied to the uppermost surface of the design in order to simulate the gravitational force exerted due to the luminaire, which is excluded from this study. A vertical load of 103.488N is applied to the uppermost surface of a plate in order to simulate the gravitational force exerted due to components excluded from this study. Where the design is subject to barrier loadings, they should be designed to resist, without damage, the loads specified in BS 6399. These are all incorporated into this study and are: A horizontal uniform distributed line load of 1.5kN/m, applied at 1.1m above FFL. A uniformly distributed load of 1.5kN/m 2, applied to the infill, i.e. the full area between FFL and 1.1m above FFL. Where the signage can be reached by members of the public, minimum impact point loads of 1kN horizontally and 2kN vertically are applied.

Conclusion We make the following observations and conclusions: The maximum von Mises stress occurs at the 2kN point load. However, this effectively represents a singularity and this therefore physically unrealistic. We can therefore ignore this stress. The maximum stress induced due to crowd loading (1.5kN uniformly distributed horizontal load and 1.5kNm -1 horizontal line load) is 3.739x10 7 Nm -2, significantly lower than the yield strength of galvanized steel, which is 2.04x10 8 Nm -2. This occurs on the lower, central sheet metal plate (part no. AJWSP10033-120-011). We conclude therefore that these loadings should not present any issues. Please refer to the image below: From the plot shown on page 44, the maximum vertical deflection occurs at the extreme end of the sign where the point loads are applied, and has magnitude 13.99mm. This represents a 32.7% increase in deflection as compared to the box section study, AJWSP10033_BOX STATIC. The highest physically realistic stress occurs at the interface between the sign which has the point loads applied and subassembly AJWSP10033-021, which has magnitude 1.592x10 8 Nm -2, quite close to the yield strength of galvanized steel. Please refer to the image below for clarification: Analyzed with SOLIDWORKS Simulation Simulation of AJWSP10033_FOLDED_ST_FR 47
Note the green areas indicating areas of high stress. The simulation suggests therefore that this is the area that will fail first. Also, since this plate is in turn connected to the sign under load, this may well explain the higher vertical deflection, as compared to the box design. It is worth considering a thicker gauge of sheet metal for this part. From pages 12-34, with the exception of Edge Weld 24 (predicted weld size 5.98mm), all reported suggestions for the weld sizes remain either below or well below 4mm. Therefore, this aspect of the design should not present any problems. Please refer to the image below for the position of Edge Weld 24: Analyzed with SOLIDWORKS Simulation Simulation of AJWSP10033_FOLDED_ST_FR 48
If we consider a typical cross-section for the box section (please refer to the image below), we obtain a moment of inertia of the area, at the centroid, about a horizontal axis rotating into the page, of 1.98x10 7 mm 4 : Analyzed with SOLIDWORKS Simulation Simulation of AJWSP10033_FOLDED_ST_FR 49
Similarly, for the folded sheet metal design (please refer to the image below), we obtain a value of 1.47x10 7 mm 4 : Therefore, we see that the folded sheet metal design is typically weaker in lateral bending than the box section design. This could also go some way towards explaining the greater maximum vertical deflection of the folded sheet metal design. We see from the Table of Frequency Mode Comparisons, given on page 46, that all of the fundamental resonant frequencies are around 8Hz, so giving a factor of safety of approximately 2 for the pass criterion of 4Hz minimum. Should a higher factor of safety be required, we offer the following additional design modification suggestions: (i) (ii) Consider varying the gauges of sheet metal for the design of subassembly AJWSP10033-120. Consider varying the height of parts AJWSP10033-120-006 and AJWSP10033-120-011. Analyzed with SOLIDWORKS Simulation Simulation of AJWSP10033_FOLDED_ST_FR 50
(iii) (iv) Consider varying the wall thickness for the 60x40 box section. Consider varying the dimensions of the folded geometry of parts AJWSP10033-120-006 and AJWSP10033-120-011. Please refer to the image below for an example area for clarification: Ideally, a design study would be appropriate, incorporating different combinations of the suggestions above, so converging upon an optimal design, or at least as close as we can get to one. Preliminary design studies have already been performed concerning and the results indicate that the suggestions given above can be very effective in pushing the fundamental resonant frequency up even further.
