Purpose and goal

Verification of a crash element that reduces the G-force in a light vehicle 1200 kg. With traditional crash structure will the G-force be about 100 % higher for the passengers in the lighter vehicle and cause injuries. The verification shows that the G-force will be similar in both vehicles in a crash due to the design of the crash element. Final test with dummy on crash test run was not able to perform due to high cost.

Results and expected effects

The result is that shows that the G-force will be similar in both vehicles in a crash due to the design of the crash element. Final test with dummy on crash test run was not able to perform due to high cost. The crash elements can be produced to a cost effective level.

Approach and implementation

The project has been done in 2 steps 1. Design and building av 2 crash elements together with the partners. We built 2 crash elements a half sphere 600 mm (front and end) and flat 150 mm thick door beam based on the concept with a fiberglass skin and 3 layers of sandwich 2. Static tests of the crash elements The verification shows that the G-force will be similar in both vehicles in a crash due to the design of the crash element. Final test with dummy on crash test run was not able to perform due to high cost.
