Title:
FREQUENCY-ADJUSTABLE COMPOSITE SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2016/201890
Kind Code:
A1
Abstract:
A frequency-adjustable composite shock absorber, comprising main moving body support legs (1) and a shock absorbing apparatus which are disposed on a basic bearing platform (6). The shock absorbing apparatus is divided into an upper shock absorbing apparatus and a lower shock absorbing apparatus. The shock absorbing apparatus is disposed on a base (301) having an internal cavity. The upper shock absorbing apparatus configured to restrain low-frequency vibration is connected, in series, to the lower shock absorbing apparatus configured to absorb additional high-frequency vibration. The upper shock absorbing apparatus comprises an elastic component based on a flexible hinge assembly (201) and a pre-stress adjusting apparatus (203). The flexible hinge assembly (201) is disposed in the internal cavity of the base (301). The pre-stress adjusting apparatus (203) configured to adjust the inherent frequency of the flexible hinge assembly is connected to the flexible hinge assembly (201). The main moving body support legs (1) are fixed to a bearing portion of the flexible hinge assembly (201). The inherent frequency of the whole flexible hinge assembly (201) is changed, such that vibrating systems of different qualities and different excitation frequencies can be effectively isolated at high and low frequency bands. The structure is simple, the adjustment is convenient, and the cost is not high.
