| Abstract: |
| By using the principle of minimum potential energy and the principle of extreme of multi-variable function ,an analytic equation was obtained in this aticle . It deals with the deflection equation and absolute maximum deflection of simply supported beam subjected to any finite parallel moving loads.The possible displacement function given in this article suits both the geometrically displacement boundary condition and the static boundary condition ,so the precision on calculating deflection of simply supported beam can be guaranteed. |
