Goal: To create a personalized helmet that meets the basic standard requirements for motorcycle or car helmets
My helmet
Created with Autodesk Fusion 360, the helmet has been proportionately measured to be able to be worn by people. I used copper material for the outer shell and supports.
My helmet has taken inspiration from the US Navy's Mark V Diving helmet and is to be worn in passenger vehicles by any person except the driver of the vehicle.
Physics and concepts
ACCELERATION: a =V/t. Change in velocity over time due to an external or apparent force. (Gravity, Normal) COEFFICIENT OF FRICTION The ratio of the frictional force to the Normal Force. CRUMPLE ZONES: Areas of an object engineered to deform and crumple on impact to absorb the energy of a collision. DRAG: Used in fluid dynamics as fluid resistance. Used in aeronautics as air resistance. INERTIA: A physical state of motion that tends to stay unchanged when no forces are acting on the system G FORCE: Force acting on a body because of acceleration or gravity. FRICTION: A force contrary to the normal force when two objects or surfaces come in contact. FORCE: Influences that cause change of movement, direction, or shape. F=ma KINETIC FRICTION: Occurs when two objects are moving relative to each other and rub together.
Reflection
Learning and constructing an original idea in Autodesk Fusion 360 had been especially tough for me. I had trouble figuring out how to use the correct tools and understanding how each tool worked. If I had to restart this project I would've watched more online tutorials for the virtual design process and created a more ambiguous helmet with a comfortable interior. After many hours at work, I feel I succeeded in creating an enjoyable helmet that can be used for safety or as a movie prop.
