Bike helmet impact absorption testing equipment   
Purpose
For helmet impact test, estimating the impact resistance of a helmet. The drop weight raised and lowered to a specified height, the computer exhibits the changing height with time, acceleration, HIC, action time and impact energy, this machine has good degree of reliability, high accuracy.

Bike helmet impact absorption testing equipment  principle
It's determined by recording against time the acceleration imparted to a headform fitted with the helmet . when dropped iwn guided free fall at a specific impact velocity upon a fixed steel anvil
