Measuring the mechanical force resisting opening of vehicle doors post-impact
Background/Traditional Approach
At the conclusion of a vehicle crash test, subjective observations are often recorded regarding the state of the vehicle doors. Common observations are "doors remained closed" or "door was open". These subjective observations are made visually by inspecting the vehicle after a crash test or by reviewing the crash films.
New Approach
A test method has been developed which measures the outward force that a door, sliding door, or liftgate is capable of resisting post impact. This provides a more objective metric for assessing the state of a door post-crash.

The test method is conducted in a complete vehicle that is anchored to the ground in such a way that it cannot move. Interior components like seats and consoles that would interfere with the force application device are removed. Additionally, the door trim panel of the tested door is removed so that the impactor (5) is in direct contact with the door inner sheet metal. The test method applies a quasi- static load to the vehicle door via a hydraulic cylinder (4), supported by a rigid arm (2) connected to a bedplate (1). The outward force applied to the door is measured by a load cell (3).
Conclusion
In conclusion, a method of measuring the outward door force that a door is capable of resisting has been presented. The method has been...
