Modeling and Parameter Identification for Rubber Bearings under Random Excitation

Based on the dynamic property test of rubber bearings a mathematical model of which is established under the condition of random excitation. The mathematical model shows that under random excitation the hysteretic restoring force is not only relevant to the displacement and the speed but also relevant to the mean value and the standard deviation of the random displacement. With the model the "force - displacement "and "force -time" relationship under different sampling segments and working conditions is reconstructed and matches well with test results. Streszczenie. Przeprowadzono testy wlaściwości dynamicznych lozyskowania gumowego przy przypadkowym charakterze pobudzen. Opracowano model matematyczny pokazujący ze nie tylko wlaściwości histerezowe wplywają na przesuniecia ale wazne są tez wartośc średnia i rozklad przesuniec.
