Summary
The basic radioactive material shipping cask-rail car dynamic simulator model, CARDS, has been modified to incorporate the following: draft gear submodels were installed for the couplers between cars, suspension subsystem submodels were installed at the front and rear trucks of the cask-rail car, a term defining the vertical friction force at the coupler face was added to the equations of motion for the cask-rail car, and the model was expanded to include equations of motion for each car in an anvil train. A simulation run was made to test the involved version of CARDS. Propagation of how the shock of impact through the train is shown as plots of coupler force between cars, horizontal displacement of each car in the train, and vertical displacements of points on the cask-rail car, as functions of time after impact. A subroutine was developed for the CARDS model to convert the displacement, velocity and acceleration response of a cask-rail car system from the time domain to the frequency domain. Some of the data recorded during the rail car impact tests conducted at the Savannah River Laboratories from July 14, 1978 through August 3, 1978 have been reduced and analyzed. The reduced data were from Test 1 and were limited to the outputs from Instruments 4, 8 through 12, and 22. Test 1 was an 8.3-mph impact of a 70-ton Seaboard Coastline (SCL) rail car with a standard coupler, carrying a 40-ton Hallam cask held in place by bolted tiedowns with stops. Results of the reduction of these limited data are presented as plots of horizontal and vertical acceeleration as functions of time, horizontal displacement as a function of time, horizontal and vertical accelerations as functions of frequency, and transfer function magnitudes as functions of frequency.
