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.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to obtain vibration and shock data during truck shipment of heavy cargo. 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.

Available in PDF, EPUB and Kindle. 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.

This book was released on 2013-03-04 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical Vibration and Shock Analysis, Second Edition Volume 3: Random Vibration The vast majority of vibrations encountered in a real-world environment are random in nature. Such vibrations are intrinsically complicated, but this volume describes a process enabling the simplification of the analysis required, and the analysis of the signal in the frequency domain. Power spectrum density is also defined, with the requisite precautions to be taken in its calculation described together with the processes (windowing, overlapping) necessary for improved results. A further complementary method, the analysis of statistical properties of the time signal, is described. This enables the distribution law of the maxima of a random Gaussian signal to be determined and simplifies calculation of fatigue damage to be made by the avoidance of the direct counting of peaks. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Available in PDF, EPUB and Kindle. Book excerpt: The fourth annual International Industrial Symposium on the Super Collider, rrssc held March 4-6, 1992, in New Orleans was a great success. Present at this year's conference were 839 attendees representing 24 universities and colleges, 34 states, 13 countries, 17 national laboratories, 11 research centers, many government entities at the local, state and federal levels, and 235 businesses and companies. This year's symposium also included 101 exhibits by 78 organizations. In all categories, this year's participation exceeded the totals of previous years and is an example of the growing support for the Superconducting Super Collider Program. This year's program had many highlights. One of the best was a message from President George Bush, read by Linda Stuntz, Acting Deputy Secretary, Department of Energy. President Bush said that each of us "can be proud of the role that you are playing in building the Collider and in setting the stage for a new era of research and discovery in high energy physics. " The 1992 IISSC's theme was "SSC-Discovering the Future. " This theme was chosen in commemoration of the SOOth anniversary of Columbus's voyage of discovery and the relationship of the SSC with discovery. This theme was articulated by all the speakers in the opening plenary session. Progress on the program was also very evident at this year's symposium. In the pictorial session, 66 photographs from all over the world were displayed to highlight progress in making the SSC a reality.
