ABSTRACT:
An airbag inflator performance test system includes: a cylindrical tank; a disk-shaped piston vertically movably disposed with a gap between the piston and an inner peripheral face of the tank, the gap allowing gas to flow; a piston rod that projects upward from the piston and runs slidably through the tank so as to guide vertical movement of the piston; a lower chamber defined within the tank beneath the piston; an upper chamber defined within the tank above the piston; an inflator disposed in the lower chamber; a pressure sensor for detecting a pressure of the upper chamber; and a piston displacement sensor for detecting a displacement of the piston in order to detect a volume in the upper chamber. After ignition of the inflator, an inflator local work and an inflator total work, which are indexes of the energy of the inflator, are calculated based on the pressure and the volume of the upper chamber.
