Currently available data were taken on trucks bearing lighter loads than the loads of current interest. In addition, the new data are expected to be useful in the determination of any trends of vibration and shock environments with increased cargo weight. These new data were obtained on a ''piggyback'' basis during truck transport of 195 700 N (44,000 lb) cargo which consisted of a spent fuel container and its supporting structure from Mercury, Nevada, to Albuquerque, New Mexico. The routes traveled were US 95 from Mercury, Nevada, to Las Vegas, Nevada; US 93 from Las Vegas to Kingman, Arizona; and I-40/US66 from Kingman to Albuquerque, New Mexico. Speeds varied from very slow during hill climbs to 101 km/hr (63 mph). A comparison of these data with a collectively reduced set of data for cargo weights varying from no-load to 133 400 N (30,000 lb) showed that the zero to peak amplitude levels of vibration were significantly lower for frequencies less than 40 Hz in the vertical axis and that there was a reduction in the vibration amplitude levels in all axes for frequencies greater than 500 Hz. The shock response amplitude was less severe for the entire frequency spectrum in the vertical axis, but it was not significantly different in the other axes. Data measurements were made on a truck shipment of a 249 100 N (56,000 lb) container over the same routes as were used for the shipment discussed in this report. These data will be presented in a subsequent report along with any additional data trends that result from studies of trucks carrying increased cargo weight.

Book excerpt: Purpose of this study was to obtain vibration and shock data during truck shipment of heavy cargo. These data were for use in determining any trends of vibration and shock environments with increased cargo weight. The new data were obtained on a ''piggyback'' basis during truck transport of 249 100N (56,000-pound) cargo which consisted of a spent fuel container and its supporting structure. The truck was driven from Mercury, Nevada, to Albuquerque, New Mexico. The routes traveled were US 95 from Mercury, Nevada, to Las Vegas, Nevada; US 93 from Las Vegas to Kingman, Arizona; and I-40/US 66 from Kingman to Albuquerque, New Mexico. Speeds varied from very slow to 88 km/hr (55 mph). A comparison of data from similar experiments with cargo weights varying from no-load to this load shows that the zero-to-peak acceleration amplitude levels of vibration are highest when trucks carry relatively light loads. This is true for the longitudinal and vertical axes of the vehicles in most frequency bands and for the transverse axis above 700 Hz. The shock response acceleration amplitudes for heavier cargo weights were less severe above 3 Hz in the vertical axis and higher between 8 and 20 Hz in the transverse axis. The highest acceleration amplitude of shock response in the longitudinal axis below about 20 Hz was produced in a trailer having a spring suspension system and carrying the 249 100N (56,000 pounds) load.

Book excerpt: The purpose of this study was to provide definitions of shock and vibration environment to which fissile material shipping containers may be exposed during normal shipment by truck and rail cars. The definitions of vibration, shock superimposed on vibration and rail coupling shock result from existing data. The dependence of shock environment, from rail coupling operations, on parameters like cargo weight and shock attenuation couplers was also studied using spring-mass models. These studies show that for rail cars equipped with standard draft gear, the cargo response decreases with increased cargo weight until the springs bottom out. For rail cars equipped with shock attenuation couplers, cargo weight has little effect on cargo response. The study also shows the importance of matching couplers and tiedown stiffnesses to decrease the cargo response. Vibration and shock data samples have been obtained during truck shipment of heavy cargo and the data will be presented in subsequent reports. Similar data need to be obtained for rail shipment of heavy cargo and during rail coupling operations with heavy cargo.
