Far-side occupants are not addressed in current government regulations around the world even though they account for up to 40% of occupant HARM in side impact crashes. Consequently, there are very few crash tests with far-side dummies available to researchers. Sled tests are frequently used to replicate the dynamic conditions of a full-scale crash test in a controlled setting. However, in far-side crashes the complexity of the occupant kinematics is increased by the longer duration of the motion and by the increased rotation of the vehicle. The successful duplication of occupant motion in these crashes confirms that a sled test is an effective, cost-efficient means of testing and developing far-side occupant restraints or injury countermeasures.

Design and Evaluation of a Guided Dynamic Rollover Test Device

Many dynamic test systems currently exist to assess rollover. This paper introduces a new test device that combines features from a multitude of different tests. It also covers the concept development, a scaled prototype design and test results from both physical and virtual tests. The Guided Rollover Test (GRT) device subjects vehicles to repeatable initial conditions by having a cart follow a guided maneuver similar to a forward J-turn with an increasing curvature sufficient to roll most vehicles. A test vehicle is carried on the cart at constant longitudinal velocity until it rolls. The cart is fitted with a tripping edge to eliminate slipping and remove the influence of tire properties and road-surface friction. Vehicles are subjected to a rollover based on their own performance characteristics which define the dynamics and consequently the roof to ground contact.
