Optimal Design of Electric Motorcycle Tubular Frame using Topology Optimization

This paper proposes a methodology for designing motorcycle tubular frames using simulation software such as MATLAB/Simulink and ANSYS, which provides an efficient and cost-effective way to approximate loads acting on the structure and topology optimization to meet performance and safety requirements. Using these tools, the design process can be simplified and reduce the number of costly physical prototypes and tests. The multi-body model developed in MATLAB® Simscape was used to approximate the loads and boundary conditions on the frame, while the ANSYS software was used for topology optimization. The resulting motorcycle frame was found to weigh 9.48 kg. The simulation results also showed that the proposed frame design met the required safety and performance criteria. The methodology presented in this paper is not limited to electric motorcycle tubular frames and can be applied to other types of vehicle frames or structures. The use of simulations allows for the exploration of different design options and the identification of optimal solutions with minimal cost and effort. The combination of MATLAB® Simulink and ANSYS is a powerful tool for the design and optimization of complex structures, providing accurate results and saving valuable time and resources.
