Abstract
This effort was undertaken as an element of a program directed at determining the shock and vibration environments encountered during the normal truck transportation of nuclear materials. Previous data for a large number of shipments have been reviewed, and over-the-road tests have been conducted. Previous efforts have resulted in an overly conservative shock spectra description of the environments anticipated during normal shipment. The present effort is aimed at predicting the actual environment. This goal is being accomplished with road simulator experiments and the continued development of an analytical model. The results of this effort will improve the capability to predict the shock and vibration environments for a given shipment and will improve the capability to design critical elements of the system, such as tie-downs. This paper will discuss preliminary experimental and analytical results. The experiments consisted of two road simulator tests. The system response and the known input resulted in defined frequency response functions for the system. Also, load cell response in the tie-downs provided explicit definition of the loads experienced by these components. These results provide data required for the development and verification of an analytical model.
