Airbag testing system  These passive safety systems must undergo various tests to be installed in vehicles. Most of the tests are carried out through destructive tests and are accompanied by all phases of airbag production. The static test system is used to test the quality of the assembly airbag module. This method USES the static deployment test (SDT), which is explained below.    When the test was triggered by a computer command, the test header was reduced to a test object almost without friction. Impact delay is measured by integrating two acceleration sensors in the test head.The arithmetic mean of the two sensors was then evaluated as test results.The impact velocity of the head on the sample is detected by two grating and the two grating are installed at a distance. A third light barrier can selectively light one or more airbags. If needed, air balloon pressure can be measured using air pressure sensors installed in the test sample container during ignition.Can use high-speed cameras to monitor and optimize the head impact test, and you can also determine the relative to the speed of ignition timing and tear and aeration time, record this in memory of up to 20000 images per second. The output of the digital stored image information is executed through the video screen, and the data is back up to video logger or dvd-rom. The camera's record begins with the ignition of the airbag module.SDT software decides to use Windows applications. The surface makes the operator familiar and easy to handle. In doing so, the software requirements that occurred during the airbag test were not ignored. It is used to analyze single-stage or multi-stage airbag systems under the same conditions as actual vehicles. This method considers the maximum possible variability, which is reflected not only in the functionality of the product but also in the storage of the measured data. For example, measurement data can be optionally stored in all common formats (e.g.,.dbf,.xls) for additional processing with other programs. Measure, calculate.Ambient temperature, 2 or 4 wire fuse resistanceThe ignition current/ignition voltage is f (t), i.e. ignition time, ignition current, ignition voltage and ignition energyTearing time (tearing open cap), airbag inflating time,Stretching and compression produced by the expansion of the wheel hub,Air balloon internal pressure measurement/temperature measurement,Long-term temperature sensingIn addition, the high-speed camera can be optionally used for analysis and research and to determine the time of tear or inflation relative to ignition time. The image can be read directly to the computer through the interface to determine the inflatable time of the airbag and so on. To do this, include an image assessment software integrated into the existing interface to avoid unnecessary program changes. This provides the possibility of subsequent processing of available image materials, such as contrast or brightness changes. In addition, text messages and graphics can also be inserted into video. Quartz control recording rate allows precise timing of processes directly related to ignition triggeringTo meet the requirements of the document, you can convert any format's digital stored image information into a standard AVI format and store it in any known media (CD and DVD drive, etc.).The user who has been authorized by the id card reader is printed on the front page for a complete check. The door of the test chamber is automatically closed and the camera is taken to the predetermined position by the positioning system. The specimens are driven by a shuttle from the automatic climate chamber and are allowed to be tested at different temperatures. The lighting system has been opened. By turning the key switch, the test piece will get the ignition pulse when the camera starts recording at the same time.After the test, the camera stops recording, the lighting system shuts down, and the room exhausts the scheduled time. Only in this way can the access door be released again. The program now stores the bar code of the component, the measurement value, all the experimental data and test Settings specified by the operator to ensure the integrity of the document. This method enables the playback performance of the test process to achieve comparable results at any time. Test evaluation is directly possible because the measurements are immediately exported on the screen. However, the application of software is not limited to airbag expansion test, but can be applied to test belt tensioner or belt restraint system.

FalCon etra MovBagAnalysis of Airbag Image Sequences  The analysis program FalCon etra MovBag extracts the outlines from airbag test scenes and derives related measurement values.Main featuresAutomatic measurement of time-varying contour graphs.Display in the image overlay and diagramEvaluation of specific measurement values:maximum expansion, area, center of gravity (output and display according to analysis system etra MovXact)Measurement of discrete points, markers or areas/patchesCalibration of results with free choice of the coordinate systemExport to Multi-D format, DIAdem® etc.The analysis program etra MovBag offers automatic measurements of airbag outlines as contour graphs = f(t). The available image processing tools are designed principally for blow-ups in a test environment; measurement methods detect differences regarding brightness and color saturation (absolute and relative to a reference image). All thresholds and parameters are adjustable.A mainly automatic measurement requires the following boundary conditions:The airbag surface is illuminated appropriately and is "bright" (in relation to the near environment).A white balance according to the color of the bag, e.g. silver, ensures a "non-colored" appearance of the airbag, i.e. the color saturation is low.The background of the scene should show a pattern helping to separate the airbag surface. Thus a (relatively) "dark" and "colored“ (as possible homogeneous)  curtain is recommendable. Measuring within a monochrome image sequence (KODAK 4540), the brightness gradient between background and airbag should be considerable.Bright or even white labels, bars etc. in the region of interest should be avoided. Nevertheless the user may select a detection area to mask-off non-relevant regions in the scene, e.g. visible spotlights.In version 1.0 the image background is assumed to be static. To measure within dynamic tests (= moving sleds) the module will be extended: trajectories (as a result of etra MovXact) allow a reference to a "running" background.ComponentsThe outlines are displayed in the image overlay: options are e.g. color, filling, background mask, coordinate system with axes and grid.An overview sketch with legends helps to log the temporal course of the expansion: options are sequence interval, increment and background mask.Calibrated graphs can be displayed as x-y diagrams or exported into table or standard files (DIAdem®).A new Multi-D data format enables a visualization as temporal sequence of 2D diagrams. Several of these diagram sequences can be displayed synchronized to AVIs, thus a comparison of different tests is possible. Of course the modules QuickView andCustomerView support this data format too.Specific measurement values are extracted from the contour graphs: maximum expansion, area and center of gravity (extendable on demand). These measurement values are calibrated and post-processed according to the extensive features of the analysis systemMovXact. Results are output numerically and as time diagrams.
