Currently, the automotive field is responsible for more than 10% of global greenhouse gas (GHG) emissions. In response to this problem, manufacturers have developed several solutions, with electric vehicles playing the leading role as a sustainable alternative. Electric motorcycles have shown a growth in sales in recent years in Ecuador; however, their growth is limited by factors such as lack of infrastructure and government regulations. Manufacturers focus on aerodynamics as a key aspect to improve efficiency; to optimize their design, tools such as wind tunnels or computational simulations are used, the latter being a more accessible option. This study proposes the design of a fairing for an electric motorcycle using CAD/CAE software, based on the IDes process. Three proposals were developed, evaluating their aerodynamic performance under the conditions of Loja province. The results indicated that design 3 obtained the best performance, with an average drag coefficient of 0.283 and a lift coefficient of -0.273, subjected to different speeds. From the structural point of view, epoxy resin with unidirectional prepreg S-glass fiber was selected for its balance between mechanical properties and cost. The simulation showed a maximum deformation of 0.35339 mm under various stresses. Furthermore, in the modal analysis, at 78.022 Hz, the fairing presented a deformation of 15.788 mm with a maximum amplitude of 6.5 Hz, validating its ability to withstand the dynamic conditions of the motorcycle without compromising its structure. |
