군 통신 쉘터의 스키드 조립체 내구성 강화를 위한 품질개선 연구

Abstract

This study aims to enhance the durability of skid assemblies in military communication shelters to prevent rubber failure. To identify the cause of rubber damage, the mechanical properties of the material used in the skid assembly were analyzed, and the standards relating to rubber were reviewed. Consequently, the cause of the rubber damage was identified as the degradation of rubber, which is a temperature- and humidity-sensitive material. To establish design strategies for the improvement of skid assemblies, skid assemblies applied to similar shelters and research papers on skid assemblies were reviewed. Then, three types of skid assemblies were designed using the considered design strategies. After designing the three types of improved models for skid assembly, the most suitable skid assembly was selected by analyzing the structural and drop impact simulations. Finally, the shape of the selected skid assembly was determined by adding a complementary material. A prototype of the selected skid assembly was tested according to the military specifications. Because the prototype met the related test items of the military specifications, the skid assembly was applied to a military communication shelter.
