The Influence of Headform/Helmet Friction on Head Impact Biomechanics in Oblique Impacts at Different Tangential Velocities

Oblique impacts of the helmet against the ground are the most frequent scenarios in real-world motorcycle crashes. The combination of two factors that largely affect the results of oblique impact

Finite element analysis of helmeted oblique impacts and head injury evaluation with a commercial road helmet

A strong recommendation is pointed out on the necessity of including rotational motion in forthcoming motorcycle helmet standards and improving the current test procedures and head injury criteria used by the standards, to improve the safety between the motorcyclists.

Critical evaluation of the SHARP motorcycle helmet rating

The Department for Transport introduced a safety helmet assessment and rating program (SHARP) for motorcycle helmets sold in the United Kingdom. The mechanics behind the part of the scheme that uses

Factors Influencing the Oblique Impact Test of Motorcycle Helmets

Using a standard surface friction for headform similar or close to that of the human scalp can ensure that the results of the oblique impact tests are more consistent and realistic.

Finite element analysis of helmeted impacts and head injury evaluation with a commercial road helmet

It was concluded that brain injuries such as concussion and diffuse axonal injury may occur even with a helmet that complied with the majority of existing motorcycle helmet standards, and the need for improving current test procedures and head injury criteria is strongly recommended.

Effects of Including a Penetration Test in Motorcyclist Helmet Standards: Influence on Helmet Stiffness and Impact Performance

Regulation ECE-22.05/06 does not require a helmet penetration test. Penetration testing is controversial since it has been shown that it may cause the helmet to behave in a non-desirable stiff way in

Impact Loading Performance Investigation of An Open-face Motorcycle Helmet with Hole in Inner Liner

The investigation of stress distribution and acceleration experienced by the helmet is analyzed by utilizing finite element method simulation, and results indicate that the hole position is not in the impact area.

The effect of the head surrogate on the performance of bicycle helmets

Inconsistent results have been reported for helmeted impact responses between the two most commonly used headforms: The National Operating Committee on Standards for Athletic Equipment (NOCSAE) and

A new oblique impact test for motorcycle helmets

Abstract A new oblique impact test for motorcycle helmets is described, simulating a fall from a motorcycle on to the road surface or the windshield of a car. An instrumented headform falls

The Influence of Reduced Friction on Head Injury Metrics in Helmeted Head Impacts

It is demonstrated that reducing friction on the surface of a helmet decreases the rotational acceleration of the head in some scenarios and increases it in other scenarios and to discuss the implications for helmet design.

Numerical simulations of motorcycle helmet impact tests

Abstract The main objective of this study was to simulate experimental impact tests on a commercially available motorcycle helmet and to develop a virtual design tool. The mechanical properties of

Head injury mechanisms in helmet-protected motorcyclists: prospective multicenter study.

A modification of the design of the helmet shell may have a preventative effect on DFE lesions, which are caused by a high amount of direct force transfer, which is an important and underestimated factor.

Survey of head, helmet and headform sizes related to motorcycle helmet design.

A test rig was built to measure rapidly and store on computer files the size and shape of human heads, and it was concluded that the current range of sizes is far from ideal, and suggestions for a betterrange of sizes are made.

Helmets for preventing injury in motorcycle riders.

Motorcycle helmets were found to reduce the risk of death and head injury in motorcycle riders who crash and suggest that global efforts to reduce road traffic injuries may be facilitated by increasing helmet use by motorcyclists.

Biomechanical Aspects of Blunt and Penentrating Head Injuries

Results providing occupant safety and vehicle crashworthiness information to the consumer from frontal and lateral impact crash tests are discussed, with an emphasis on head injury assessment and mitigation.
