摘要The shock absorption test of the EN1078 standard is the focal point of this study. These
performances are to setup a shock absorbing system for commercially available helmet, to measure
the key parameters when an instrumented helmeted headform drops onto anvils. In this test, the
helmet quality is assessed by measuring the acceleration time history of a headform during a helmeted
headform impact. Helmet quality is expressed in terms of the injury parameters: maximum resultant
linear headform acceleration of the headform's center of gravity and Head Injury Criterion (HIC).
Besides, the present study performs to develop and validates a finite element of helmeted headform
impact test. The FE model obtains by the scanned shapes of a bicycle helmet. The headform and anvil
design in accordance with EN 960: 2006 and the EN1078 specification, respectively. This study
performs finite element analyses of helmet impact tests using LS-DYNA software. The results of the
present method fit the experimental results well, implying that the numerical method is a practical
approach to helmet design problems. Furthermore, the helmet test model proposed here has potential
for guiding the future development of helmet technologies.
