PROJECT OVERVIEW
Our esteemed Client is a subsidiary of the renowned TATA group, which happens to be India's largest conglomerate. They are currently engaged in the development of a cutting-edge 5G Remote Radio Unit (RU) that complies with the ORAN 7.2x standards. Recognizing our expertise in the field, the Client has entrusted us with the responsibility of conducting Finite Element Analysis (FEA) for an assembly comprising the Remote Radio Unit, mounting pole, and antenna. The primary objective of this analysis is to thoroughly examine the dynamic behavior of the Remote Radio Unit and ensure its optimal performance and reliability, in strict accordance with the industry standards outlined in ETSI EN 300 019-2-4 V2.4.1. We are honored to have been chosen for this significant project and are committed to delivering exceptional results. In this project, we performed FEM analysis to check strength of the triband antenna model for the given load conditions. FEM analysis is carried out as per the load conditions provided by the customer. We carried out Modal Analysis, Sine sweep Analysis (Harmonic Analysis), Random Vibration Analysis, Shock Analysis, Seismic Analysis, and Wind load Analysis.
ETSI EN 300 019-2-4 V2.4.1 STANDARDS
In the telecommunications industry, ETSI EN 300 019-2-4 V2.4.1 is an important standard for evaluating the environmental conditions to which telecom equipment may be exposed during stationary use at non-weather protected locations. It defines the relevant environmental conditions and severities that equipment must be designed to withstand, helping engineers assess its reliability, durability, and operational performance under real-world conditions. By understanding and applying this standard, engineers can identify potential environmental risks, establish appropriate design and qualification requirements, and evaluate equipment resilience against factors such as temperature variations, humidity, vibration, and other applicable environmental stresses. This systematic approach helps ensure the structural integrity and long-term reliability of telecommunications equipment, supporting consistent performance throughout its intended service life.
FEA MESH
FEA model of the enclosure assembly of Triband Antenna consists of approximately 3.8 million nodes and 2.1 million elements, utilizing higher order Tetrahedral and Hexahedral elements. To ensure proper functionality, appropriate contacts have been defined between all the parts in the assembly. Furthermore, the necessary material properties and boundary conditions have been applied.
FEM ANALYSIS CASES CONSIDERED
Sine Sweep Analysis in X, Y and Z directions Random Vibration Analysis for Test Severity Shock Analysis for Characteristic Severity & Test Severity Seismic Analysis for Zone 4 as shown in the curve Wind Load Analysis for different mounting condition
FEM ANALYSIS RESULTS
A comprehensive technical report is submitted to the client, documenting the results of the structural and dynamic analyses performed on the Triband Antenna assembly. The report includes detailed stress contour plots to identify critical stress concentrations, deformation plots to evaluate the structural response under the applied loading conditions, and factor of safety calculations to assess the assembly's structural integrity against the specified design criteria. Additionally, the frequency–acceleration response graph is provided to illustrate the dynamic behaviour of the structure across the relevant frequency range and identify potential resonance conditions. These results enable the client to evaluate the structural performance, verify compliance with the applicable requirements, and make informed decisions regarding design adequacy and reliability.
