Design and Dynamic Performance Analysis of Tunable Lattice- Based Vibration Energy Dissipation Structures

Abstract

This research aims to explore the working principle, performance characteristics, and application scope of a performance-adjustable vibration reduction and energy dissipation structure through design and experimentation. Through this research, we hope to address the problems of traditional passive energy dissipation devices, improve the efficiency and accuracy of vibration control, and contribute to the development of the field of vibration control. The study focuses on comparing the influence of boundary conditions and structural parameters on the dynamic characteristics of pyramid-shaped and hourglass-shaped lattice-filled structures, and investigating the superior vibration reduction and isolation performance of both structures at the same relative density.
