Title: ANSYS Explicit Modeling for Prospective SAVY Designs and Worst Case Impact Orientation during Drop

Abstract

A preliminary experimental drop test of a new 5.5 gallon SAVY-4000 container at a 12 ft height resulted in an impact angle of approximately 26 degrees and significant deformation of the locking ring and locking collar. Subsequently, the SAVY failed leak tests following the drop test. Based on previous analyses on SAVY containers, the primary modes of failure were determined to be vertical drops directly over the lid for the larger diameter sizes. The tests were initially bounded by the 45 degree impact angle. It was necessary to determine if a new bounding case existed at or near an impact angle of 26 degrees. In addition to characterizing the drop angle, modifications to the existing SAVY components were applied and analyzed to determine if container deformations could be minimized. Figure 1 includes the primary drop configurations investigated. A parametric study was conducted to determine the sensitivity of lid and collar deformation as a function of impact angle.
