چکیده مقاله
In different applications, optimal values of an impact damper parameters impact mass, elastic coefficient of barrier etc should be found in order to damp undesired vibrations efficiently The main target of this work is modeling and investigating the behaviour of a kind of impact dampers Our model incorporates Hertzian contact between the impact mass and the barrier In next step, due to the strong non linearity of the model, the homotopy perturbation method is used to solve the governing equation of the main mass motion To confirm the accuracy of this method, results are compared with numerical solutions Next, a systematic approach based on a genetic algorithm optimization method is used to determine the best design parameters for suppressing vibrations Finally, optimum parameters for complete quenching of vibrations are obtained
