ANALYTICAL SOLUTION OF MASS EQUATION, NONLINEAR SPRING WITH EFFECTIVE WIND FORCE UNDER DYNAMICAL LOAD

In this paper, green function and transfer function are used for analytical solution of mass equation, nonlinear spring with effective wind force. This equation has been used to model space structure, wing and all of the structures used at high altitude. Furthermore this equation is applied frequently in modeling foundation similar to nonlinear spring and the equation is better solved analytically where answer of the analytical solution is similar to the mechanical action.
