The concealment is one of the most important issues in the design of military structures. Therefore, the dynamic behavior of systems must be analyzed such that these systems must be hidden from the enemy in the field of war. Usually, the dynamic behavior of systems is modeled by differential equations, which is also one of the important branches of applied mathematics and it is updated continuously. The resulting differential equation is linear or nonlinear. The Linear mathematical model leads to the ordinary differential equations and has quick solutions and their analysis is very simple. The nonlinear models lead to the partial differential equations models, and show the characteristic of the system that is not predicted by linear models. For exact investigation of the behavior of a system, one can consider all the details of system and obtain complex differential equations. Then the concealment and retrofit of civil defense is satisfied using the interpretation of its solution. In this paper, the general structure of the modeling of vibrations systems is investigated and it is shown that what are the applications of vibrations in the military industries and how it can be used to proceed the civil defense purposes using real examples.
