摘要：

This paper studies a conservative nonlinear oscillator with odd nonlinearities, u ″ + f(u) = 0 , the square of its frequency is f ′ (u i ) , where u i is a location point. A criterion on how to choose a location point is given. Dufffing equation is used as an example to show the accuracy of the prediction. © 2016, Springer India Pvt. Ltd.
