| Abstract: | A strongly nonlinear system with large parameter is transformed into a small parameter system by using the modified LP method.The frequency-response function of the new system is determined by the multiple scales method. A method for determing the approximate frequency-response function of strongly nonlinear system is presented. 4refs. |
