| 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. |
