【Abstract】 The difficulty of Symplectic method to find the response of a classical damped system is expounded.Based on a strategy that a classical damped system may be transformed into an undamped system equivalently,a Symplectic method to get the response of the system with classical damping,with the help of Symplectic solution of undamped system,is proposed.A detailed analysis of Symplectic method for undamped system response is carried out.Results of examples show that the method proposed is efficient and feasible.更多还原
