Advanced Side Impact System:

The ASIS is world’s first side impact simulator which can reproduce multiple intrusion areas at the same time to provide more realistic results than any other simulator system before. It allows a much more detailed view on the crash phenomenon without causing high costs.

ASIS is a powerful tool that can be used in a very early phase of car development. The system is designed to deliver informative results about quality of door panel, airbag, foams, plastics and other parts of the inner cabin of a car which are relevant for the occupant's safety. Especially these parts are still very difficult to simulate by FEA which makes the ASIS an essential test system in any automotive safety lab.

Air pressure up to 200 bar in a cylinder is accelerating a stable ram. The acceleration of the ram is modulated by hydraulic brakes that are controlled by an ultra fast valve. Therefore acceleration, speed and way are controlled very precisely – for each single cylinder.

DSD provides two types of ASIS, an On-Sled and a Static version.

The On-Sled version is completely seated on an acceleration sled system. The ASIS will be shot together with the sled and the door actuators are reproducing the relative intrusion.

The Static version is delivered with an own, separated seat sled while the door actuators are creating the absolute stroke of intrusion. In both cases the sled is simulating the movement of the seat/car body.
