Helmet Project
PURPOSE
This helmet is designed for the off-road dirt bike rider and features the following safety features for maximum protection.
Overview
ACCELERATION This helmet design helps in acceleration because of its elimination of friction and drag. While you are positively accelerating there is minimal friction due to drag which helps you accelerate faster.
COEFFICIENT OF FRICTION I will use this air resistance formula to calculate the coefficient of friction on the helmet and what could be done to reduce even more friction.
CRUMPLE ZONES The helmet features crumple zones around the temple, forehead, and occipital bone to provide minimum damage to those areas. IT does this by crumpling when the helmet absorbs an impact in that area. The helmet does not have crumple zones everywhere or it would be too weak and not functional.
DRAG This helmet design reduces drag by minimizing surfaces that are perpendicular to the direction of motion. This allows air to travel past and not create drag in areas that are flat.
INERTIA The inertia that occurs on the rider when an impact occurs can vary throughout the body. This variation can be deadly if not properly addressed. This is why the helmet features upper neck support to prevent from whiplash that can result in a broken neck.
G FORCE
This chart shows how much g Force can be exerted on a human and the affects it will have. The goal of this helmet is to reduce the amount of g Force on the specific areas of the head to prevent concussions. This will be done by creating crumple zones that absorb g forces.
FRICTION
This dirt bike helmet features a sleek design of molded high grade carbon fiber formed for minimal friction. The face guard is curved for decrease in wind resistance along with the visor to eliminate friction.
FORCE
This helmet features a carbon fiber design for maximum strength when high amounts of impact force occur on it. This helmet is not made of plastics or Polycarbonates because they cannot withstand the impact forces that carbon fiber can.
KINETIC FRICTION
The helmet features a slick coating that comes in a variety of colors to reduce kinetic friction between the helmet and the air. In addition this slick coating helps reduce friction between the helmets and objects so the riders helmets slides off of any objects it encounters.
Report on Research
I started this project by deciding what type of helmet i wanted to design and what some of its design flaws were. The helmet i chose to make was a dirt bike helmet for offroad use and identified that problems from experience with the current helmet i have. With this in mind i researched all the topics that i needed to address and encorporate how my design would use these areas to make the helmet better. I discovered that the main areas of improvement could be used in the material and crumple zones. I designed my helmet to feature a stronger carbon fiber shell and have crumple zones around the temple, forehead and occipital bone. The following are the sources i used for my research.
