Abstract
Bell crank is an important mechanical component in force transmission systems that requires design optimization to improve structural efficiency. This research aims to analyze the effect of topology optimization on stress distribution, displacement, and safety factor in bell crank design using Finite Element Method (FEM) simulation with Autodesk Fusion 360 software. The mass retain variations studied include 90%, 80%, 70%, and 60% on three material types: Aluminum 6061, Carbon Steel, and Alloy Steel. The research results show that mass retain reduction from 90% to 60% significantly increases von Mises stress. The highest stress occurs at 60% mass retain with a value of 166.398 MPa (Aluminum 6061), but remains below the material's yield strength. displacement also increases with mass reduction, with Aluminum 6061 showing an increase from 0.786 mm to 1.198 mm. Although the safety factor decreases, the lowest value remains above the critical limit (SF > 1.5), proving the design remains safe. The G-code generation process was successfully performed using CAM simulation, producing an NC program with 72,295 lines of code and a machining time of 23 minutes 2 seconds. Topology optimization proves effective in reducing mass up to 40% while maintaining the structural integrity of the bell crank.
