Abstract
A composite frequency-adjustable shock absorber is provided, comprising a motion main machine stand bar and a shock absorption device, which are arranged on a foundation carrier platform; the shock absorption device is divided into an upper shock absorption device and a lower shock absorption device, the shock absorption device is arranged on a base with an inner cavity, and the upper shock absorption device for suppressing the low-frequency vibration and the lower shock absorption device for absorbing additional high-frequency vibration are connected in series; the upper shock absorption device comprises an elastic component based on a flexible hinge group and a prestress adjusting device, the flexible hinge group is arranged in the inner cavity of the base, the prestress adjusting device for adjusting the inherent frequency of the flexible hinge group is connected with the flexible hinge group, and the motion main machine stand bar is fixed on a load bearing portion of the flexible hinge group. The inherent frequency of the whole flexible hinge group is changed, so the high frequency band and the low frequency band of vibration systems with different masses and different excitati…
