Analysis of static characteristics of a motorcycle swing arm of a twin-shock suspension type using the finite element method

Abstract

Motorbikes need a swing arm or swing arm to connect the rear wheel to the frame. Static loading is important in planning the main motorbike so that it can run safely. Swing Arm is the main structural part of a motorcycle chassis that serves to hold the rear wheels for driving and as a shock breaker support. The swing-arm is free to follow the road contours and vehicle loads as long as the motorbike moves. This study aims to determine the condition of the motorcycle swing arm static type twin-shock suspension. This type is chosen because it is most widely used by consumers. This research was carried out by making 3D models of swing arms made from carbon steel models. Analysis of static loading on the swing arm structure was simulated using software based on the finite element method so that the value of von stresses and displacement was obtained. The results of the analysis concluded that the swing arm has good characteristics because the maximum von mises voltage of 43.55 MPa is smaller than the total thickness of 350.0 MPa, and the maximum deformation is 0.003923 mm.
