| Abstract: | A mathematical model of double mass torsional vibration system is established with quadratic nonlinearities.By using the method of multiple scale under the conditions,the first approximation solution and its corresponding steady-state solution,the theoretical and numerical analysis is made and steady-state curves are obtained.It is pointed out that the resonance has abundant dynamic phenomenon including jumps and amplitude-frequency response curves of system will be changed with the changing of forced excitations amplitude F1 or F2. |
