A technique for investigating nonlinear vibrations

Tóm tắt

In this short comumnication the main ideas of the method of equivalent linearization and dual conception are further extended to suggest a new technique for solving nonlinear differential equations. This techinique allows improving the accuracy when the nonlinearity is strong and getting nonlinear featurea of responses. For illustration the Duffing oscillator is considered to demonstrate thc effectiveness of the proposod technique.
