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 Telecom Industry, the European Telecommunication Standards (ETSI EN 300 019-2-4 V2.4.1) is widely recognized as a standard of utmost importance. It plays a critical role in ensuring the reliability and performance of equipment. By delving into this standard, Engineers can develop a comprehensive understanding of its significance and how it contributes to maintaining equipment integrity in various environmental conditions.
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
Modal Analysis: Modal Analysis looks for Natural Frequencies and Normal modes of a structure. We can find the natural frequencies of an object so that we can create or avoid resonance. 99% of the time we want to avoid resonance to protect the structure.
HARMONIC ANALYSIS RESULTS
Detailed report explaining factor of safety calculations, Stress plots, deformation, Frequency- acceleration response graph is submitted to the Client.
