Abstract

The brake pads made from asbestos are environmentally hazardous due to the friction and abrasion occurring during braking, resulting in the release of airborne asbestos fibers. These fibers pose various health risks to humans and contribute to environmental pollution. This study aims to analyze the influence of adding clamshell waste material on the mechanical properties of motorcycle disc brake pads. The research utilized an experimental approach, conducting tensile and friction tests on six samples with different compositions: 100% brake pads, 40% brake pads, 60% simping clamshell, 60% brake pads, 40% simping clamshell, 20% brake pads, 80% simping clamshell, 50% brake pads, 50% simping clamshell, and 100% brake pads. The results indicate that the sample comprising 50% used brake pads and 50% simping clamshell exhibited the smallest difference in thickness, measuring 0.05 mm or 0.59%, indicating the strongest adhesive strength and wear resistance compared to other variations. Thus, a higher simping clamshell composition sacrifices some tensile strength but offers improved elasticity, benefiting specific braking conditions.

Abstract

This study aims to analyze the effect of variations in the chassis configuration of an electric vehicle prototype on structural performance using the Finite Element Analysis (FEA) method. The chassis was designed using 6061 aluminum with a C-channel profile in three configuration variations: H, X, and Y. Three-dimensional modeling and simulation were performed using Autodesk Inventor 2025 software based on a total static load of approximately 1,668 N, derived from an assumed mass budget of 170 kg for a single-seat prototype, was applied at the driver's feet, seat, and backrest, and at the motor and battery mounts, representing the weight of the driver and vehicle components. The analyzed parameters included the distribution of von Mises stress, displacement, and the safety factor to determine the most optimal chassis configuration. The simulation results showed that all variations met the safety criteria, as they had a safety factor of 15. The H-pattern configuration produced a maximum von Mises stress of 18.13 MPa with a displacement of 0.70 mm; the X-pattern produced a stress of 17.17 MPa with a displacement of 0.57 mm; while the Y-pattern produced the lowest stress of 16.48 MPa with a displacement of 0.59 mm. Based on a comparison of these three parameters, the Y-pattern configuration provides a more even load distribution, resulting in the best structural performance compared to the H and X patterns. The research findings indicate that variations in chassis geometry affect stress and strain characteristics, and can therefore serve as a reference in the development of prototype electric vehicle chassis designs that are lightweight, safe, and have good structural strength.
