Abstract

The increasing number of motorcycles used as daily transportation demands structural components with high strength and reliability, particularly the swing arm, which directly receives static and dynamic loads from road conditions. This study aims to optimize the swing arm design of the YAMAHA MX KING 150 monoshock type by improving the initial geometry using the Finite Element Method (FEM). Simulations were conducted on two design configurations—initial and optimized—under two loading categories: static loading (component load, rider load, and full load) and transient dynamic loading generated by excitation forces from a speed bump. The analyzed parameters included von Mises stress, total deformation, and Safety Factor (SF). The optimized design produced a maximum static stress of 15,548 MPa with a deformation of 0,22169 mm, achieving a Safety Factor of 11,963. Under dynamic loading, the structure also demonstrated strong stability, with a maximum stress of 22.325 MPa, peak deformation of 0.76648 mm, and a minimum Safety Factor of 9.314, indicating the component’s effective ability to absorb impact loads. Overall, the optimization resulted in significant improvements in structural strength, stiffness, and safety. The updated geometry achieved a more uniform stress distribution and lower deformation response, leading to enhanced structural performance under various loading conditions.
