A Study on Building a Motorcycle Finite Element Model for Crashworthiness Base on the Current Transportation in Vietnam

This study aimed to construct a finite element model of a small motorcycle with full deformability for simulating frontal crashes, and to provide a comprehensive guide for the entire development process. The Honda Wave 110 cc, a Vietnamese national motorcycle, was selected as the physical motorcycle, and the model was analyzed in the LS-DYNA environment. This paper presents a tutorial on advanced 3D modeling to generate a high-quality 3D geometry and replication model of a motorcycle chassis, and then to set up a model dummy sitting on the motorcycle. This motorcycle FE model can be utilized for crashworthiness analysis and other studies. The motorcycle model was constructed from different materials such as steel and aluminum to make the motorcycle chassis model. The frame of the motorcycle was created by combining the individual parts of the saddle, handlebar, and wheel. The entire model of the motorcycle was then meshed and assigned materials, and its stability was assessed by conducting a crash simulation with a vehicle model. The dummy part was also added to the motorcycle model so that it could be employed to assess the injury of motorcyclists when a collision with other types of traffic occurs.
