According to the VDI guideline 3633 "simulation" is a method for reproducing a system with its dynamic processes in an experimental model to gain insights, which are transferable to the reality. Furthermore simulation means the preparation, implementation and evaluation of specific experiments with a simulation model.

The "crash simulation" is a physical experiment, in which a test sample (vehicle body or test rig) is adapted on a test sled. This sled is accelerated or delayed, in order to simulate the stresses of a real vehicle crash. The advantage is, that the test sample won't be destroyed, but will be reusable. Thus the crash simulation allows testing single components or systems, e.g. for the development of restraint systems.

ACTS uses a hydraulic motor, which accelerates the trolley. Colloquially it is named "sled test". The test objects can be tested separately or built into the body in white. In this way a complex complete vehicle crash tests can be avoided and thus the costs can be reduced.
