Function Test Bench Rollbar

The Function Test Bench Rollbar system has been built for 100% production test of double roll-over bars. For the design a manual loading and fully automatic test performance concept is used.

During the test sequence the installation of attachment parts on the one hand and the following characteristic values of the roll-over bars on the other hand are measured:

• Electrical values of the pyrotechnical release elements
• Various heights of roll-over bars
• Push in force, release force, unlocking force
• Release times and distinctive release curve

The measurement equipment includes contactless laser displacement measurement systems and various fully integrated force sensors.

After a successful test run the roll-over bars are marked. An integrated label printer creates a unique label for each roll-over bar. The pyrotechnical release elements will be fixed by means of a monitored electrical screw driver system.
