Design and simulation of a Mine Proof Mechanism

Abstract

The issue of security is very paramount in every organization. The traditional mine proof vehicles with a solid plate hull provide protection against very small IED (improvised explosive devices) & MINES. This led to lives being lost more due to physical injuries by shock produced and a large change in momentum in very small time, that made organs over pressured and fatality. The present analysis deals with the application of a mechanism filled with Nitrogen gas to provide the cushioning effect of damper and using that pressure and Kinetic energy of gases to be utilized in acting against the mechanism forcing the compressed gases to break the safety valve and move into a reserve container which has various attachments and the pipes of steel take that heavily pressurized air into the compartment. The compartment having an inserted airbag type structure will be filled with air and it will make the compartment a big air stuffed structure to damp shockwaves. The designing and the strength analysis of the structure is done with the help of CATIA & ANSYS. The result was not very different except we achieved a reduced chance of physical and secondary deaths. The flat hull was then replaced by a V shaped hull which shown a reduction in 66% of pressure concentration on the vehicle hull. By using the combination of damping container system and a V monocoque hull the blast force was mainly diverted and the overall casualties can be reduced.
