Simulasi Perpindahan Panas Pada Area Rolling Mill Plate 1 Project Menggunakan Finite Element Method (FEM)

Abstract

Three-phase electric motors often experience overheating, which can affect their performance and reliability, especially in industrial applications. This overheating is usually caused by inefficient heat transfer between machine components such as the motor, shaft, and rolling plate. This study analyzes temperature distribution and cooling load in the rolling mill plate system using the Finite Element Method (FEM). Simulations were conducted with various meshing sizes (150 mm, 210 mm, 300 mm, 400 mm, and 500 mm) to evaluate their impact on temperature and cooling efficiency.The simulation results show that meshing size affects steady-state temperature and cooling rate, with the highest temperature recorded at 150 mm meshing and the lowest at 500 mm meshing. At 500 mm meshing, the component temperature decreased from 1000°C to 216°C, and the cooling load was reduced from 599 W/m² to 225 W/m². These findings indicate that larger meshing sizes provide more efficient cooling, highlighting the importance of meshing size selection in thermal analysis. This study supports the design of more optimal cooling systems to prevent overheating and improve the operational efficiency of electric motors.
