With the rapid development of the electromagnetic gun in military field of study, theworld military power pay widely attention to the application prospects of magnetic gun. I-mproving the performance of guns using new electromagnetic launch technology.This paper mainly studied the effect factors of the launching about electromagneticgun orbit under the role of linear, nonlinear load distribution stress deformation factorsand solving analytical solutions of the electromagnetic gun tube under linear, nonlinearfunction distribution pressure, finally getting the conclusion by having verified theexperimental data.Firstly, studing the influencing factors of deflection about the damping force, so itcan be improve electromagnetic emission device performance and enhance the firingprecision, focusing on the damping force’s main effect. The article firstly introduced theelectromagnetic launch rail device’s working principle, model and the method of solvinganalytical solution of high order partial differential equation. It establishes theoreticalfoundation on solving higher order partial differential equations.Secondly, it discussed analytical solution of the control equation, that is to say the def-lection change with travel time, and then focused on main influence factors about deflecti-on change of beam, calculated and analyzed by programming the deformation of beamexpression the linear and nonlinear model using MATLAB software according to the differ-ent models, it is shown that the damping factor differently affecting the change of deflecti-on, thus can be selected has little effect materials on deflection change so as to achieve th-e purpose of prolonging device life and improving the precision of emitting. It is of greatsignificance to promote the practical process of the electromagnetic gun.Again, discussing the analytical solutions of the electromagnetic gun tube under thespecial function distribution pressure, and giving the limit of guns infinite long tube is fam-ous Lamè formula.Finally, The experimental results are in accord with the theoretic calculation whenstrain values of a barrel are recorded by static strain tester on REG-III electromagnetic launcher’s barrel, so verifing the correctness of the theoretical calculations.
