The frontal 40% overlap deformable barrier crash test is used to evaluate vehicle safety performance in frontal collisions with partial overlap. In this test, the vehicle is driven at a specified speed into a deformable barrier, with the front end overlapping 40% of the barrier width.
Compared to the full-frontal 100% overlap rigid barrier test, the 40% overlap deformable barrier test represents a partial-overlap collision scenario, which more closely simulates real-world accidents where only part of the vehicle front impacts an object.
During the test, vehicle safety performance metrics are assessed and recorded, including:
Structural integrity
Occupant protection
Airbag deployment
Seat and seatbelt effectiveness
More representative of real-world partial-overlap collisions
Allows comprehensive evaluation of vehicle safety performance under partial frontal impact
Cannot simulate collisions at different angles, speeds, or with different types of obstacles
In summary, the frontal 40% overlap deformable barrier test is a widely used regulatory test for evaluating vehicle safety in partial frontal collisions, providing a realistic assessment of performance in real-world crash scenarios.
