| Abstract: | An integral equation of non linear dynamics is presented. An explicit precise integration algorithm with four order accuracy and self correct to solve this equation is given. This method is adapted to solving the non conservative systems with multi DOF and strong nonlinear. Numerical examples show that the method can give results with high accuracy and needs less labor. |
