Title:
LOW-FREQUENCY VIBRATION ISOLATION SUPERSTRUCTURE UNIT, SUPERSTRUCTURE AND SUPERSTRUCTURE DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2023/092533
Kind Code:
A1
Abstract:
Disclosed in the present invention are a low-frequency vibration isolation superstructure unit, a superstructure and a superstructure design method, which can solve the problems of it being difficult for a vibration isolation device to meet requirements for miniaturization and weight reduction, and a reduction in the structural rigidity and strength due to vibration isolation. The low-frequency vibration isolation superstructure unit comprises: an external protection structure (1), an internal mass block (2) and a bending structure (3), wherein the external protection structure (1) is of a concave structure, and a side thereof having an opening is vertically placed; the internal mass block (2) is disposed on the side of the external protection structure (1) close to a vertical inner wall, and the internal mass block (2) is only connected to the bending structure (3) on the side of the top of the internal mass block (2) close to the opening of the concave structure; and the bending structure (3) is disposed on the side of the external protection structure (1) close to the opening, and the bending structure (3) comprises M U-shaped structures (18) spliced in a vertical direction, a top vertical beam (12) and a top transverse beam (13).
