Recipe for Simultaneously Achieving Customizable Sound Absorption and Mechanical Properties in Lattice Structures

Advanced Materials Technologies, Год журнала: 2024, Номер unknown

Опубликована: Сен. 4, 2024

Abstract Lattice structures with customizable acoustical and mechanical properties show significant promise as practical engineering materials. However, the geometry of traditional lattice simultaneously dictates both properties, alterations in one impacting other, leaving little room for customization. Herein, leveraging mechanism Helmholtz resonators, a general recipe is presented to independently introduce sound absorption structures. The component based on perforated plate, while truss structure. Through high‐fidelity analytical acoustics model developed, finite element analysis outlines range achievable through proposed design encompasses effective absorption, characterized by resonance peak coefficient ≥0.7, across almost every frequency broad from 1000 5000 Hz, within thicknesses 21 25.5 mm. Also, diverse stiffness strength, large‐strain deformation modes, can be achieved implementation different trusses. Finally, concept validated experimentally 3D‐printed samples. This innovative approach allows tailored creation that specifically address requirements applications.

Vibration and Bandgap Characteristics Analysis of Pyramid Cylinder Lattice Skeleton Structure

Advanced Engineering Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 12, 2025

Lattice structures have attracted significant scholarly attention due to their exceptional mechanical properties, including lightweight characteristics and high strength. Their multifunctionality, such as energy absorption vibration reduction, adds versatility. While extensive research has been conducted on the reduction performance of plate‐type, shell‐type, truss‐type lattice structures, studies cylindrical are comparatively limited. To achieve broadband suppression in this study proposes a novel structure based pyramid cells. The bandgap formation mechanism skeleton examined, with quantitative analysis influence structural parameters using normalized indicators. Results indicate that demonstrates multiple bandgaps within 0–1500 Hz range, exhibiting substantial attenuation capabilities. Additionally, adjusting enables shift toward lower frequencies. Finally, experimental verification finite element model performed by comparing transmission curves maximum relative error −7.48% at resonance peak. This work offers valuable insights for application noise control fields.
