[Abstract]:The resonant mechanism of bilinear hysteretic oscillators is studied theoretically and experimentally. The mechanical model of dry friction damping vibration isolation system is established, and the low frequency locking characteristic is studied. The analytical solution of unlocking frequency is obtained, and the system parameter relationship under the optimal solution is determined. The time response process of the system is numerically calculated by using the motion equation, and the theoretical results are verified by experiments. The conclusion is of great significance to the rational design of the non-resonant vibration isolator.
