Experimental and finite element analysis of pole mounting bracket for performance and mass optimization

  Uday Kumar Singh,  Abhishek David

Two pole mount brackets for 50kg RRU is modelled and analyzed for wind speed 67 m/s when RRU is mounted at the height of 40m from ground level. Software used for modelling is SOLIDWORKS. Experimental and FEA analysis was executed for Model 1 bracket for testing the sustainability of bracket for wind load. Based on these results model 2 bracket is designed for better performance, material savings and low stress concentration area for same loading conditions. All loading conditions are calculated based on standard TIA 222-G. FEA analysis is performed with the help of ANSYS software. The results obtained after performing the analysis shows the difference in the structural behavior of the bracket. Since RRU is very much complex in shape it is replace by a same weight of dummy. An average dummy size is considered and analysed. After testing both brackets withstand all static but model 2 is much more efficient in terms of weight and maximum stress observed in body is also less in model 2 bracket. Bolt pretension used for bracket-to-bracket clamping and bracket to dummy clamping is 20NM.Materail used for bracket is high tensile steel.
