Practice on Design Project 2

 HAYABUSA Keisuke
Course description
In this exercise, we will digitally design the body that has both aerodynamic performance and design for "Mini 4WD". In this project, the design target is limited to the outer body, and we determine the optimum shape while evaluating the aerodynamic performance by CFD (Computational Fluid Dynamics), and manufacture the body by 3D addtive manufacturing. Finally, a mini 4WD time trial using the manufactured body will be held, and a design contest will also be held.
Purpose of class
The purpose of this exercise is to learn the following.
・ 3D-CAD (Fusion360) * Only operations related to body creation
・ Aerodynamic performance evaluation by CFD or wind tunnel experiment * Only operations related to aerodynamic performance calculation
・ Reverse engineering and shape optimization technology
・ Manufacturing technology by 3D additive manufacturing
・ Aerodynamic performance evaluation by time trial using actual machine
・ Ability to apply the knowledge learned in basic subjects to manufacturing, Improving imagination
Goals and objectives
  1. You can do the 3D-CAD digital design and the reverse engineer technology.
  2. Aerodynamic performance can be evaluated by CFD and mini wind tunnel experiments.
  3. Based on the 3D-CAD data created individually, some parts can be manufactured by 3D additive manufacturing and their characteristics can be explained.
