A Field Performance Prediction Technique for Light Truck Structural Components

A method has been developed which allows prediction of the field performance of structural components based on prototype vehicle test procedures and results. Component designs can then be optimized by selecting prototype durability test objectives which more accurately reflect actual field usage. This procedure, which is based on fatigue damage calculations from component strain histories, has been successfully applied to non-safety related body, frame and suspension structural components of light trucks and vans.
