Lightweight shell device for transponder antenna

Abstract

The invention relates to a lightweight shell device for a transponder antenna. The lightweight shell device comprises a metal top cover, a metal box body, a non-metal bottom cover and a circular connector, wherein the metal top cover is arranged at one end of the metal box body and fixedly connected with the metal box body; the non-metal bottom cover is arranged at one end of the metal box body and fixedly connected with the metal box body, and the circular connector is arranged on the side face of the metal box body; and the metal box body takes light weight and rigid strength as optimizationobjectives, adopts a finite element method and takes the wall thickness of a light weight shell as a design parameter to carry out rigidity matching to obtain a wall thickness parameter. Compared with the prior art, the lightweight shell device has the advantages of light weight and the like on the premise of ensuring the rigidity.

Description

technical field [0001] The invention relates to a transponder antenna housing, in particular to a lightweight housing device for a transponder antenna. Background technique [0002] The transponder antenna is an important part of the railway train control system and an important train-ground wireless communication device. As a vehicle-mounted electronic device, the transponder antenna is installed on the locomotive bogie or vehicle body. The ground beacon is activated within a certain area by sending a power carrier. After the beacon is activated, the fixed message information is sent back to the transponder antenna for processing, thereby realizing vehicle communication. [0003] When the transponder antenna passes the electrical center point of the beacon, it is necessary to accurately detect the positioning signal of the beacon center point, and the positioning error shall not exceed ±5cm. At present, the height range between the transponder antenna center and the beaco...

AI Technical Summary

Problems solved by technology

Since the installation position of the transponder antenna is located on the bogie or the bottom of the vehicle body, the weight of the existing transponder antenna itself is relatively high, and the strength requirements for the vehicle installation structure are relatively high. In order to ensure the reliability of the installation, the vehicle manufacturer needs to design rigidity Large and high-strength installation hangers increase design difficulty, manufacturing cost and structural weight

In addition, the heavier mechanical structure will also increase the labor intensity of the installation and commissioning personnel
