A Finite Element Investigation into the Impact Performance of an Open-Face Motorcycle Helmet with Ventilation Slots
Motorcycle helmets are essential for reducing the risk of head injuries in the event of an impact. However, during the design of helmets, a compromise must be made between user safety and user comfort. Accordingly, the present study proposes a novel open-face helmet design, in which the helmet features three ventilation slots in the upper-head region. Finite element analysis (FEA) models were c...
متن کاملEffect of Italy's motorcycle helmet law on traumatic brain injuries.
OBJECTIVES To evaluate the impact of a revised Italian motorcycle-moped-scooter helmet law on crash brain injuries. DESIGN A pre-post law evaluation of helmet use and traumatic brain injury (TBI) occurrence from 1999 to 2001. SETTING Romagna region, northeastern Italy, with a 2000 resident population of 983 534 persons. PARTICIPANTS Motorcycle-moped rider survey for helmet use compliance ...
متن کاملAeroacoustic sources of motorcycle helmet noise.
The prevalence of noise in the riding of motorcycles has been a source of concern to both riders and researchers in recent times. Detailed flow field information will allow insight into the flow mechanisms responsible for the production of sound within motorcycle helmets. Flow field surveys of this nature are not found in the available literature which has tended to focus on sound pressure leve...
متن کاملA Proposed Modeling Method in Finite Element Slope Stability Analysis
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...
متن کاملHelmet laws and motorcycle rider death rates.
We investigated motorcycle rider death rates between states with full motorcycle helmet laws and those without. This was done using both unadjusted bivariate analyses and multivariate random-effects generalized least squares regression models of rider death rates. Multivariate models were adjusted for the competing influences of several explanatory variables, including the existence of a motorc...
