AI Technical Summary
Existing dynamic vibration absorbers cannot simultaneously adapt to the three-dimensional vibration of the equipment base, occupy a large space, have low structural integration, and require pre-tightening force to adjust stiffness, resulting in poor adaptability.
Design a three-dimensional dynamic vibration absorber that uses an integrated U-shaped elastic component. Stiffness matching is achieved by adjusting its geometric section parameters, eliminating the need for preload. Four U-shaped springs are integrated to provide three-dimensional elastic support, and the outer shell is welded to the base plate to form an integral rigid structure.
It achieves three-way vibration reduction of the equipment base at the same frequency or any frequency, with a compact structure, simple assembly, strong adaptability, and is suitable for space-constrained scenarios such as ships.
