Response of a Two-Degree-of-Freedom Vibration System with Rough Contact Interfaces by Zhiqiang Huang, Xun Peng, Gang Li, Lei Hao

“…By analyzing the undamped free vibration, it was found that the variation of the second-order natural frequency with amplitude increases with rougher contact interfaces; however, the amplitude has little influence on the first-order natural frequency of the system. For the harmonic excited analysis, the jump frequencies and hysteretic region both decrease with rougher contact interfaces. …”
