Make vehicle rotation visible - Denton COE offers model 3200 rollover display system
One of the test scenarios in crash test applications is the vehicle rollover test. For the visualisation of the vehicle position in the rotation phase, IES has
developed a combined system to make the rotation angle visible for the high speed cameras.
The system consists of three major components. The control unit powers the angular rate sensor and calculates the
rotation angle using the sensitivity of the sensor which is stored on an internal ID-module. This angle information is continuously sent to a display which illustrates the rotation angle. Inside the angular rate
sensor, there is also a tilt sensor for measuring the initial (start) angle of the vehicle prior to the rollover. Both values, the dynamic and static angle can be used in common DAS- systems for further processing
and evaluation.
