Personalized 3D Helmet

Evidence of work

In this project, we have been tasked to design a concept Formula One race car helmet or any other helmet using Autodesk® Fusion 360. The helmet had to support the highest degree of safety and comfort to the user. The design aesthetic must convey speed and the style and culture of Formula One racing. Our key learning objectives with this task were:

  1. Create a 3D model of a helmet using Autodesk Fusion 360

  2. Define relationships between the elements of the helmet and build the assembly

  3. Generate photo-realistic images of the helmet

  4. Describe how helmets provide impact protection by dissipating crash energy

  5. Explain Newton 2nd Law of Motion

  6. Calculate impact force

  7. Explain how friction and mass effect motion

  8. Describe the general structure and material used to create a helmet

Reasons Why Our Helmet Meets the Safety Standards

Safety

  1. Hard outer shell to protect from impacts, heat, and flying objects

  2. Outer shell also creates a “crumple zone” in case of a crash

  3. Air vents to protect from overheating

  4. Covers the whole head and face for optimal protection

Comfort

  1. Inner lining inside the hard shell to fit more comfortably

  2. Air vents to help with getting oxygen inside

  3. Not too tight around the head

  4. Visor so that nothing gets in your eyes

Content

ACCELERATION - a change in speed over a period of time; the higher the acceleration, the faster the change in speed. For example, if a car goes from 0 miles per hour (mph) to 60 mph in 2 seconds, it is a higher acceleration than if the car goes from 0 mph to 40 mph in 2 seconds. Acceleration is a rate of change of speed; NO change means NO acceleration. If something is moving at constant speed, it is NOT accelerating.

COEFFICIENT OF FRICTION - the measurement of the level of friction embodied in a particular material. The formula is μ = f/N, where μ is the coefficient of friction, f, is the amount of force that resists motion, and N is the normal force. Normal force is the force at which one surface is being pushed into another.

CRUMPLE ZONES - areas of an object designed to deform and crumple in an impact, as a means to absorb the energy of a collision. The fronts of most automobiles are designed as crumple zones to protect the passengers from frontal collisions.

DRAG - a term used in fluid dynamics that is sometimes referred to as air resistance or fluid resistance. Friction is one of multiple factors that influence the amount of drag encountered by a body moving through a fluid such as air or water.

INERTIA - when an object remains still or moves in a constant direction at a constant speed.

G FORCE - a force acting on a body as a result of acceleration or gravity, informally described in units of acceleration equal to one g.

FRICTION - a force that resists motion when two objects or surfaces come in contact.

FORCE - causes masses to accelerate; they are influences that cause a change of movement, direction, or shape. When you press on an object, you are exerting a force on it. When a robot is accelerating, it does so because of the force its wheels exert on the floor. Force is measured in units such as pounds or newtons. For instance, the weight of an object is the force on the object due to gravity (accelerating the object towards the center of the earth).

KINETIC FRICTION (or dynamic friction) - occurs when two objects are moving relative to each other and rub together (like a sled on the ground).

Reflection

During this project I felt that we had some terrible time management skills. Our group wasn't able to complete all of the necessary tasks before the due date, and although we turned them in eventually, we should have been focusing on this assignment more so that we could get it in when Mr. Tronconi wanted them. Another thing we need to work on due to this project is critical thinking. When we were creating our helmet we weren't really basing it on anything specific, just creating it, and then we did the research afterwards. What we should have been doing was researching BEFORE we started and then creating the helmet based on our research.

One thing that I excelled in during this project was communication. I was able to talk with my team and able to ask questions when I needed help or was confused on something. This was a group project, so I was able to lean on my team members when I got stuck or needed some creativity. Another thing that I did well on was planning out the tasks that needed to be done. I always find that if I take a few minutes to write out everything I need to do and make myself a schedule, it is very helpful in my success in the project. Overall, I am very proud of the work that me and my team created.
