Description

The horizontal airbag test system essentially consists of two modules, the acceleration unit for the test bodies and an airbag holder for the greatest variety of types and sizes of airbags. This device enables one or two test bodies to be accelerated hydraulically and either guided or allowed to fly freely into an airbag or any other type of structure desired. To measure acceleration reliably in the forward direction, each test body is fitted with two acceleration sensors. During airbag testing, four force sensors at the airbag holder record the forces acting on the airbag. In addition to measurements of force and acceleration, the displacement and speed of the test bodies can also be measured in both the forward and backward directions (rear impact analysis). Since two bodies can be used, meaningful tests can also be carried out for front and rear passengers using large airbags. In addition to airbag testing, this equipment enables tests conforming to ECE-R12 to be carried out.

Software

This software was designed especially for the horizontal airbag test system. It is based on CrashSoft®3 which is already working successfully in complex crash test facilities. The software protects the operator from operating errors as far as possible, but gives him free access to the test system parameters. The characteristic features of CrashSoft®3 such as extensive test preparation, test execution and evaluation are implemented for the horizontal airbag test system in a similar manner to the CrashSoft®3 facility control. The unique unit control edit and view fields enable the displayed units to be changed using a pull down menu. If a numeric value has already been entered, then the displayed value is converted automatically. As has been customary for the MESSRING facility control for many years, the peripheral equipment like air extraction, lighting and video are operated and displayed via user interface.
