This paper describes the development of a Dynamic Door Component Test Methodology (DDCTM) for side impact simulation. A feasibility study of the methodology was conducted using a MADYMO computer model by taking parameters such as door pre-crush, door-to-SID (Side Impact Dummy) contact velocity and the deceleration profile into consideration. The prove-out tests of this methodology was carried out on a dynamic sled test facility. The DDCTM has been validated for various carlines. In addition, various existing dynamic component test methods are reviewed. In our approach, a pre-crushed door, mounted on a sled, strikes a stationary SID at a pre-determined velocity. A programmable hydraulic decelerator is used to decelerate the sled to simulate the barrier/door deceleration pulse during door-to-SID contact period. This test procedure provides excellent correlation of the SID responses between the component test and the full-scale vehicle test.

This paper provides an overview of the Side impact Research program conducted by Vehicle Methods and Components Department of Ford Motor Company over the past three years. A simple spring-mass computer simulation model is developed for predicting crash behavior of the body side structure of a vehicle impacted on its side by another vehicle. The model was used in determining the degree of structural reinforcement required to effectively reduce body side intrusion of a compact size vehicle. Exellent agreement between the predicted and test results was obtained and the effectiveness of structural reinforcements in reducing occupant cushioning requirement was demonstrated.
