Low driving range has been a major setback while considering the use of compressed natural gas in automobiles. Michigan Tech and REL designed and developed a new CNG tank, with improved storage availability. Drop tests were conducted on these CNG tanks at the REL facility. The tanks were dropped from 1.83 meters (6 feet) height above ground, while maintaining different positions. The primary objective of these tests was to evaluate the damage resistance of the CNG tank. Because, in order to meet the NGV2 standards, the tank should contain the gas safely even after it suffers severe impact.

The objective of this study is to simulate these drop tests using finite element analysis. This will be done by using various FEA packages like HyperMesh, HyperView and LS-Dyna.
