Abstract

The aspect of modern warfare is gradually changing to a network of warfare, and its central information electronic warfare is evolving every day. Recently, domestic equipment of electronic warfare, which have succeeded in domestic localization, are strongly influenced by the nature of the environment. Therefore, the structural reliability of the antenna switching module that connects the mast and antenna of the ES equipment is the most important. This study proposed a structure that has an improved structure of antenna switching module by currently analyzing the structure of the antenna switching module and the environmental influence. By modifying the structure of the antenna switching module welding method and part of the reinforcement block, the structure was improved and the validity of the improved antenna switching module was simulated using a load test. The simulation showed that the safety factors of antenna switching module welding point and reinforced block part was enhanced 5.3 and 1.5 times compared to the existing values. These values were verified by load (181kg) test results, which was each 3.7Mpa and 64.4Mpa. The load test results were similar to the simulation results and load supporting capacity of the proposed antenna switching module was enhanced.
