AI Technical Summary

Technical Problem

Traditional passive vibration damping devices suffer from problems such as narrow tuning band, large size and weight, or parameter sensitivity under low-frequency, multi-modal dense, or wide-frequency excitation conditions. Existing superstructure solutions have insufficient end load input efficiency, deformation dispersion leading to low energy consumption efficiency, and difficulty in controlling frequency drift in low-frequency multi-modal engineering scenarios.

Method used

A modular superstructure vibration damper based on water-elastic origami connecting units is adopted. By arranging water-elastic origami connecting units between mass blocks, they can undergo compression, shearing, folding and unfolding or local torsional deformation when relative displacement occurs under external excitation. Combined with multi-layer series structure and viscoelastic energy dissipation design, adjustable dynamic characteristics are formed.

Benefits of technology

It achieves high flexibility and adjustable dynamic characteristics within a limited space, improves the effect of low-frequency vibration control, and has the ability to reduce vibration and adjust parameters within the target frequency band. It is suitable for array expansion and applicable to superstructure vibration reduction systems of different scales and topologies.

Abstract

本发明涉及结构振动控制技术领域,公开了一种基于水弹折纸连接单元的模块化超结构减振器。该减振器包括多个质量块、设置于相邻质量块之间的水弹折纸连接单元以及设置于所述水弹折纸连接单元端部与所述质量块之间的刚性耦合连接结构。所述水弹折纸连接单元由片材或层合片材折叠形成三维连接体,并沿相邻质量块之间的连接方向设置为多层串联结构;优选地,各层折纸单元均为可变形结构,并由两个对向布置的六折痕水弹折纸子单元以及位于二者之间的两个过渡单折痕折纸子结构拼接形成,拼接后构成整体连续的空间折叠构型。相邻折纸层之间优选采用端面直接接触拼接方式连接,层间不设置独立刚性隔板。所述刚性耦合连接结构优选包括钢端板与胶黏层,分别设置于质量块端面与水弹折纸连接单元端部之间。该减振器构型明确,连接关系清晰,便于模块化组装与阵列扩展,可作为宿主结构的外挂式减振模块应用于低频振动控制及多模态响应抑制。
