Forensic Engineering Analysis Of Dot Verses Non-Dot Helmet Performance As A Function Of Velocities Exceeding Standardized Testing As A Function Of Velocities Exceeding Standardized Testing

Abstract

Motorcyclists Suffer Serious Trauma More Often Than Automotive Occupants Tracing To Contact With Non-Yielding Road Surfaces And/Or Direct Impact From Other Vehicles. A Motorcycle Helmet Is The Principal Defense To Head Impact. If A Motorcycle Helmet Passes Dot, Department Of Transportation, Approval, What Performance Improvements Correlate? Dot And Non-Dot Helmets Were Tested To Determine Impact Performance At Velocities Exceeding Standardized Testing Velocities. Three Types Of Dot Approved And Three Types Of Non-Dot Approved Helmets Were Tested At Two Speeds Outside Of The Federal Testing Standards In The United States. The Analysis Was Performed Using An Inverted Pendulum Sub-System Experimental Device With A Hybrid-Iii Anthropometric Dummy Cranium And Neck. Results Quantify The Performance By Category, Model, And Experiment By Test Metric.
