This device was designed by Battelle Laboratories
for the US Army. Although the design is proprietary, it's not classified.
The original detailed solid model was created with SolidWorks. DeepSoft, LLC. created a substantially simplified model of just the structurally
significant components also in SolidWorks. This model was then transferred to
Algor via InCAD for creation of a FEA model. Four corners were modeled
individually for drop impact via vector steering to force the g loads to follow
an axis from the device Center of Gravity (CG) to a selected impact corner.
Fixed boundary conditions were placed on and around the fixed impact corner
under study. The FEA model consists of an assembly
of 74 parts plus 9 major components which were modeled as point microscopic beam
masses and located with virtual beam elements. This was nearly a 2 million
Degree of Freedom (DOF) model which is a fairly complex model. Color bars were removed to hide proprietary
data.
