“…Over the period 1976 to 1983, the Hanford Engineering Development Laboratory conducted a study to determine the extent to which the shocks and vibrations experienced by radioactive material shipping packages during normal transport conditions are influenced by, or are sensitive to, various structural parameters of the transport system (i.e., package, package supports and vehicle). The results of this study were documented in a series of 17 reports and two papers: October 1, 1978-December 31, 1978(Fields and Mech 1979b 7. Dynamic Analysis to Establish Normal Shock and Vibration of Radioactive Material Shipping Packages, Quarterly Project Report, January 1, 1979-March 31, 1979(Fields and Mech 1979c 8.…”

This report fulfills the M4 milestone M4FT-13OR08220112, "Report Documenting Experimental Activities." The purpose of this report is to document the results of a literature review conducted of studies related to the vibration and shock associated with the normal conditions of transport for rail shipments of used nuclear fuel from commercial light-water reactors. As discussed in Adkins (2013), the objective of this report is to determine if adequate data exist to realistically evaluate the impacts of the shock and vibration associated with the normal conditions of transport on commercial light-water reactor used nuclear fuel shipped in current-generation high-capacity rail transportation casks. The literature review concentrated on papers and reports related to the transport of used nuclear fuel, radioactive waste, or other radioactive material, in part because of the weight associated with commercial light-water reactor used nuclear fuel rail transportation casks, which is about 300,000 lb., and because the weight of the transportation cask on a railcar directly affects the magnitude of vibrations and shock imparted to the used nuclear fuel contained in the transportation cask. In addition, the railcars that will be used by the U.S. Department of Energy to ship transportation casks containing used nuclear fuel from commercial light-water reactors are required to meet American Association of Railroads (AAR) Standard S-2043 (AAR 2008). Therefore, searches were also conducted for studies where the railcar met AAR Standard S-2043. Because the focus of the modeling described in Adkins (2013) is at the fuel assembly and fuel rod levels, studies where accelerations were measured on fuel assemblies or fuel rods were also especially relevant. During the literature review conducted of studies related to the vibration and shock associated with the normal conditions of transport for rail shipments of used nuclear fuel, over 200 documents were collected from a wide variety of sources, including studies performed by Sandia National Laboratories, the Hanford Engineering and Development Laboratory, Ontario Hydro, Battelle Columbus Laboratories, and the Savannah River Site, as well as studies performed by other investigators. The results of the literature review follow.  There were few recent studies of the shock and vibration associated with the normal conditions of transport. Most of the studies that were related to the shipment of used nuclear fuel, radioactive waste, or radioactive material were published in the 1960s, 1970s, and 1980s. Relatively few studies were published after the mid-1990s.  No studies were found that evaluated a rail transportation cask or other cargo that was similar in weight to the weight of a commercial light-water reactor used nuclear fuel rail transportation cask, about 300,000 lb. The largest transportation casks evaluated were in a study by Prulhiere and Israel (1980), where the TN 12 transportation cask, weighing 220,000 lb., was evaluated; and in a study by Pujet and Malesys (1989), where the...

“…Finally, ''white-box'' approaches based on mathematical expressions depending on the parameters of the draft-gear components (e.g. friction coefficient, wedge angle, and spring stiffness) are followed by Hanford Engineering Development Laboratory, 31 University of Western Australia, [32][33][34] Centre for Railway Engineering and Queensland Rail, 35,36 and Russian researchers. 37 Moreover, a ''white-box'' technique was used by Cheli and Melzi 38 in an upgraded version of TsDyn.…”

Longitudinal train dynamics have a significant impact on both safety and performance of railway systems. Numerical simulation of long heavy haul trains can thus provide essential information for the development of diagnostic and signaling systems as well as coupling elements and braking systems. Long trains are usually modeled by considering only the longitudinal degree of freedom and by adding extra resistant forces to represent the track curvature and gradients. The prediction of in-train forces represents the most critical aspect in modeling the longitudinal dynamics of long trains made up of several vehicles. In fact, coupling elements have non-linear force–deflection characteristics, with different behavior in loading and unloading states, thus featuring a hysteretic loop. Look-up tables storing data from experimental tests are generally used to model these elements; however, other strategies, such as fitting curves and white-box models are witnessed in the literature. Recently, an international benchmarking of longitudinal train dynamics simulator was established in order to compare the output results obtained by different models with the same input data. The research group from Politecnico di Torino performed the simulations using the multibody software Simpack, but computational inefficiencies and numerical divergences occurred. To overcome these issues, a new dedicated in-house code was developed in the MATLAB environment. The paper focuses on the description of this new code and its validation, which was carried out by performing the simulations according to the benchmark inputs and comparing the results with the outputs from the other participants.
