Lightweight,High-Strength Fiber-Reinforced Composite Communication Rod Structure Design

With the progress of the times,a new generation of broadband mobile communication technology,that is,the fifth generation of mobile communication technology(referred to as 5G)came into being,5G communication technology has the advantages of high speed,low delay and large connection,is the cornerstone of the network to realize the interconnection of people,machines and things.Comparing 4G and 5G networks,5G has increased power consumption by more than three times,but the coverage of 5G networks is not ideal,so 5G requirements for the number of base stations are very high.Communication towers are important infrastructure to expand the coverage of 5G communication technology,and their structural performance is directly related to whether the communication towers can operate stably and safely,and is an important cornerstone for promoting the continuous development of communication technology.In this paper,new materials with Strength,light weight,excellent thermal insulation characteristics,corrosion resistance and other characteristics are adopted,and the overall structure design of composite communication towers is realized according to the relevant technical standards and requirements in the construction and application of communication towers at home and abroad,as well as the standard requirements commonly used in the construction and use of materials.Using the simulation capability of ANSYS platform,the influence of rod segmentation and node connection mode on the structural performance of composite communication tower was studied and analyzed.Optimize the connection method of metal flange sleeve,optimize the connection method of inner sleeve and outer clamping inside and outside.The force of each section of the composite communication pole tower is evaluated by theoretical calculation,and the design wind pressure including the communication equipment(antenna)and the main pole of each section is calculated.By utilizing the simulation and simulation capabilities of ANSYS systems,finite element simulation of composite communication towers was formed based on the finite element research capabilities of the software and referring to the key data in the composite communication tower.According to the nonlinear problem of composite communication towers,and drawing on the load analysis specifications of each working condition of existing communication towers in China,the finite element analysis and simulation research of the motion state of composite communication towers under wind load are carried out.The finished rod body was prepared,the 6m long rod body was tensile bending experiment to determine the relationship between displacement and force,and the sample rod with the key elements of the complete composite communication tower was assembled,and the true shape experiment simulating wind load was carried out.The results show that the use of glass fiber/polyurethane composite materials in communication towers is not only effective,but also has a good application prospect.Moreover,the structural design of the 18 m height composite communication tower is reasonable,and the design scheme of pole segmentation and node connection method is practical and effective.The overall design of the composite communication tower is in line with the reality and design specifications.
