Vibration simulation of transportation environment to predict failure in portable tanks

摘要

AbstractThe purpose of this study was to simulate transport vibrations and to develop a technique to evaluate the performance of chemical tanks that had been approved by existing US Department of Transportation test methods. The containers tested were six different types of portable tanks used to ship chemicals. The tanks had a capacity of 250–300 gallons (USA) and contained liquids with a specific gravity of 1.1–1.2. Fractures were seen in some of these tanks as a result of transportation. These were attributed to high vibration magnification factors developed during transport by truck. The bottom panels were stiffened by providing added thickness to the plate and also by welding the elbow to the bottom plate. This reduced the magnification factors and increased trip l
