| With the rapid progress of mobile telecommunication, especially the gradual improvement of the third generation mobile telecommunication (3G), mobile telecommunication is expected to transfer to 3G from 2G before long. While the foreign telecommunication manufacturers are developing service cars to further promote 3G, it is urgent to design 3G service demonstration cars to suit the situations of our country.Through the design and research of the first domestic 3G service demonstration container, the main research contents and key technology for the container are put forward in this paper, the design scheme for the general layout of the container, the constitution of main components and primary technique specifications of the container are described, and the application of the container is also introduced. Finite-element analysis method is used to calculate, compare and analyze the strength of two types of container-body steel structure to adjust the strength and rigidity of the container. Engineering methods are applied for the thermal design and parameters calculation of the container body, and the thermal performance are tested on the spot to verify the rationality of temperature control design. Stability calculation principle is used to adjust the stability calculation of the mast. And to improve the reliability of the container, how to apply the vibration-proof technique to control the vibration of the telecommunication equipment in the container is also studied.The design and research in the paper provides theoretical and experimental bases for the design and development of series of telecommunication demonstration containers. The container designed in this paper has been put into use to demonstrate 3G telecommunication products of independent intellectual property of our country at home and abroad. The performance and specifications of the container have met the expected design requirements. It has played a role in the wide spread of advanced 3G products of our country. |
