How we do it
As the title suggests, statistic vehicle (XL) tests can be done without the vehicle being in driving mode. With this type of test a compressive force is applied to the walls to be tested. Mostly the procedure is as follows:
- A steel frame is inserted into the truck. This frame is built in at a few centimeters distance from the wall to be tested. It must be well-anchored into the truck because it will have to capture the reaction forces.
- Between the wall and the built-in frame an air cushion is inserted.
- The air cushion is blown up by means of compressed air
- Based on the surface of the air cushion and the actual air pressure, the load on the wall can be calculated.
If both plastic and elastic deformations with a particular load remain within the specified limits, the wall can be certified.
