High-Pressure Cylinder Test for Airbag Inflation
ProjectThe basic idea of airbags is that when a car is involved in a collision, steel cylinders filled with highly compressed gas rapidly inflate airbags in the center of the steering wheel, the dashboard, and sometimes other places, to cushion driver and passengers, reducing and preventing injuries. A high quality automotive airbag system cannot ignore the quality of the reservoir cylinders, because if a cylinder were to burst, the high velocity gas might project cylinder fragments into the surrounding areas as well as people and cause significant injuries.
The various types of steel cylinders must undergo the relevant cylinder verification tests during the manufacturing process. Among them, the two most important are the fatigue and burst tests.
- The fatigue test must be able to conduct continuous tests by automatically adding and reducing pressure by pre-configured amounts.
- The system must be able to record the testing data and calculate the relative pressure and time curves.
