Shaquira-Taiquana Jashanna Tyteyana Patriciana Yoseline They're speaking japanese. Shoei helmets are made and tested in JAPAN! And even your top brands like Bell and FOX, AGV are made in China, but they go through quality control and homologations to be certified ECE, DOT.
A large area makes contact, but the blunt of the initial force is generally kept to a fairly small area. But I agree, this does just seem to be a puncture test.
When Shoei were testing the x-spirit 2 over 4000 shells were used. Out of those 4000 I'm sure they'd tested a flat surface too. Oh and this was tested from a height double what the EU testing body thinks will suffice for they're testing. So if you want to tell the world that one of the biggest helmet brands in the world have a fatal floor in the testing of they're helmets, maybe become a shoei technician so that you actually have a clue about what your on about. Just saying...
Yeah that is true, it just seems like this is more of a puncture test - thereby just testing the material rather than the helmet structure. Maybe that's what they're trying to do... If you look at a helmet that has been crashed in real life though, they don't have a little dot where it contacted the ground, the material is flexible, so as it crashes, a larger surface area contacts the tarmac. This video just shows that if someone hit you with an ice pick, you might be alright
tubeengineer you're no engineer, real engineer here you should know that on a flat surface this would distribute the load over a larger surface area so the force applied to the helm would be ALOT less than that of a point.
What did you use for your release mechanism? We are testing helmets for the football industry and are trying to find a simple release mechanism to use.
tubeengineer u can hit a sharp angle coming out of a pole or bridge the are simulating that cuz not always u'll be riding on track road and highway have these kind of object
I know I might be a bit late for this but hitting with a point would be ALOT worse than hitting a flat surface as the pressure is what breaks the equipment that's why stress is measured in pascals. By hitting with a point you're getting a higher pressure with the same amount of force as P=F/A with A being area. If anything this would then be an over simulation of a real world example
Hahahah LoL many many time, try to crushed by tour bus including with the passenger, i' m sure your helmet and its contents (fake head) will shattered in pieces, today i still doubt that there is a helmet that can resist if crused by tour bus.. cause in real life i'm watching a dead man who had been killed by the tour bus , his head hollow and his helmet crushed.. sorry so many accident in the street and crushed by tour bus isn't a strange incident anymore
now i know laughing professionals have tested my helmet
This is why i buy a shoei helmet made in china tested in china for china exported to USA.
Made in Japan and tested in Japan... Never will be manufactured or tested in China!

+Jorge Spat Shoei is a top brand...
+Marq Shoei are made in Japan by hand

please test fire helmets from various brands and prices to find out which extinguisher helmet is superior when on duty

shoei is quality. thats why the price is up there :D
Better than M2R?
With all the crazy people with illegal weapons in my area, I could use this helmet:)
Better because there is smaller pressure because the force is coming from a larger area. Easy physics
What did you use for your release mechanism? We are testing helmets for the football industry and are trying to find a simple release mechanism to use.
A flat surface connecting to a rigid curved surface results in only one small point taking the majority of force.
this is one of many test an elmet has to pass
PERFETTO!!!!
Tell us all how energy works Mr.Troll.
shoei is the best
Is that qwest?
its snell certified
衝撃と圧力は違うぞ
That is not the air tunnel testing
Can you do Masei helmet test?
SD - Pa
So good to know these guys take their job serious. *sarcasm*
Lol, Theres nothing wrong with having fun as long as you also stay focused and work hard! 😁
Its not safe.at a speed of 100+
When shoei
A typical real world crash would involve a flat surface hitting the helmet, not a small point. I'd like to see how it would perform like that instead.

Jiahahhahahahahajajajajajjajajajajajaja
Bell helmets are American. AGV Italian...
Lol
Lol :-)
