Head Drop Test Response GESAC, Inc

Slide 15

Biofidelity of Head Response After the sham was composed and tried, we understood that the head reaction in drop tests are higher than the reaction of dead body heads in comparative tests which is around 60g. The head can be tuned to that reaction if the client demands it. GESAC, Inc

Summary - 1 A 3.4 kg newborn child biofidelic, instrumented sham has been produced. Anthropometric particulars were produced from direct estimations and scaling. Affect reaction passageways were scaled from grown-up effect reaction hallways. Affect tests demonstrate that sham either meets or is near sought passages. GESAC, Inc

Slide 33

Summary - 2 The sham is instrumented to gauge increasing speeds at the upper and lower neck, trunk CG, head CG, and pelvis. A damped rib structure permits the trunk affect reaction to show practical hysteresis. GESAC, Inc

Slide 34

Summary - 3 String potentiometer on the rib permits estimation of trunk pressure. Rakish speed sensors in the head permit coordinate estimation of head precise speed. GESAC, Inc

Slide 35

Summary - 4 Load cells at the base of the neck and on the lumbar spine empower estimation of hub strengths on the cervical and lumbar spines. Bundled FlexiForce sensors indicates guarantee as an effect stack estimation gadget when tried on pieces of froth upheld in the back. GESAC, Inc

Slide 36

Summary - 5 FlexForce sensors appear around 80% of the heap levels appeared by load cell on impactor. FlexForce bundle on the guts demonstrates a low level of constrain when contrasted with the impactor stack cell. This marvel will be explored in future. GESAC, Inc
