DESCRIPTION The ECE moving barrier is used in performing tests to determine the safety of occupants in the event of a side impact in compliance with the requirements of ECE R95 according to Trans/SC1/GRSP/R48/Rev1, with deformation components that can be obtained from various manufacturers. The moving deformable barrier is equipped with a hydraulic-pneumatic brake that prevents a secondary impact on the test vehicle, and can also be used as an emergency braking system (in the case of an aborted test, for instance).

BRAKE SYSTEM In order to be able to decelerate the moving barrier in case of emergency and after the impact, a vehicle brake system is installed which operates the disk brakes. Figure 5 shows a moving barrier with hydropneumatic vehicle brake; as an alternative, the moving barrier is also available with a hydraulic vehicle brake. Wireless remote control or control via trailing cable Failsafe operation (automatic actuation in case of cable brake or power blackout) Controllable via CrashSoft facility control software Figure 4: Hydraulic-pneumatic brake system Figure 5: Braking system mounted on moving barrier Page 4 / 7
BRAKING OPERATION The moveable barrier is equipped with a brake system, which prevents the barrier to hit the target vehicle a second time after the impact. Tha brake system can also be used to trigger an emergency stop of the barrier, in case of the abortion of a test. The brake system is mounted on the center of the main frame and is coupled to the four disk brakes on each wheel. This ensures that each wheel is braked simultanously. In the case of a necessary abortion of a test, the brake can be activated with the emergency stop button. The signal will then be send to the brake system via the attached trailing cable, or optionally wireless with a remote radio signal. The brake is aktivated by deasserting the 24V control signal from the brake. This ensures that the braking mechanism is also triggered in the case of a cable break or power blackout.
