Studi komparatif variasi ketebalan pelat baja ASTM A36 main steel sebagai penopang baterai torpedo

Abstract

This simulation aims to conduct a comparative study of the thickness variations of ASTM A36 steel plates to determine the most optimal thickness for supporting the weight of torpedo batteries. The analysis focuses on the values of the von Mises stress, displacement, and safety factor parameters. Mechanical engineering in the field of maritime defense is an important aspect, one of which is torpedoes that use battery energy as their main energy source. The battery support is the main focus of this study, which will compare the optimal thickness variations for the battery. With the development of technology and the demands of manufacturing digitalization, the production process has begun to use simulations on Computer-Aided Engineering (CAE) software, making conventional testing more efficient. Through SolidWorks software simulation, a static study was conducted to analyze each variation. ASTM A36 steel plates measuring 1400 mm in length, 70.6 mm in width, and varying thicknesses of 1 mm, 2 mm, and 3 mm were adjusted to the weight of the battery. A total of three 5 kg battery blocks were used in this torpedo. ASTM A36 material was selected due to its high yield strength. The optimal strength of the battery holder was achieved through simulation in SolidWorks. The results of each thickness variation were then processed using a comparative study to obtain the optimal thickness based on a comparison of von Mises stress, displacement, and safety factor.
