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 val
