Abstract
The development of the automotive industry, particularly in commercial vehicles such as trucks, demands structural design improvements capable of supporting heavy loads without compromising safety and efficiency. One of the most critical components is the chassis, which serves as the main structural support of the vehicle. This research aims to optimize the load-bearing strength of the Isuzu GIGA FTR truck chassis, especially after the frame is extended. Theoretical foundations in this study include the basic concepts of mechanics of materials, stress and strain, and the finite element method (FEM) for structural analysis. The main material used is SS540 steel with a yield strength of 400 MPa. The method employed is a static linear simulation using SolidWorks 2021 software, comparing four design variations: the initial design, an extended chassis (optimization 1), and two optimized designs with the addition of crossmembers (optimization 2 and 3). Simulation results show that the third optimized design, which includes an additional crossmember in the middle of the chassis, yields the best performance with a deformation of 6.2262 mm, maximum Von Mises stress of 129.32 MPa, strain of 0.00066448 mm/mm, and the highest safety factor of 3.09. Compared to the initial and first optimized designs, the third design is proven to be safer and more efficient in distributing loads. The conclusion of this research is that the addition and placement of crossmembers in strategic positions significantly enhance the chassis’s structural strength and stability. It is recommended that any chassis extension should be accompanied by structural evaluation and appropriate reinforcement. Further studies are also encouraged to include dynamic load analysis and experimental testing to obtain results that better represent real-world operating conditions.
