Analysis of Load and Lubrication State of Racks and Pinions of Three Gorges Ship Lift Based on Actual Service Conditions

open access: yesJixie chuandong, 2023
The rack and pinion of the three gorges ship lift is a low speed and heavy load open gear transmission with hard tooth surface. Once the lubrication is poor, it is easy to cause damage such as tooth surface scuffing, which will affect the operation ...

Design of Multi‐Cell FDM Build Bed Systems for Optimal Material Usage in Additive Manufacturing Process

open access: yesMaterial Design &Processing Communication, Volume 2026, Issue 1, 2026.
Support structures are essential in additive manufacturing (AM) processes such as material extrusion, particularly for fabricating parts with overhanging features. However, conventional supports are typically removed after printing and cannot be reused, resulting in significant material waste and increased printing time.

Study on the Mechanical Properties of a High‐Force Inerter Damper: Experimental Investigation

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Inerter damper is a two‐end‐point acceleration‐type damper with significant mass amplification and negative stiffness characteristics, which has been widely studied in recent years. However, the inertance and inertia force of the current inerter dampers are relatively small, and their relevant energy dissipation mechanisms are still unclear, which ...

Inerter Chain−Embedded Finite Locally Resonant Meta‐Foundations for Enhanced Seismic Protection of Liquid Storage Tanks

open access: yesStructural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Liquid storage tanks exhibit complex dynamic behaviors under seismic excitation due to fluid−structure interaction, where resonance effects amplify sloshing, elevate hydrodynamic pressures, and increase the risk of structural damage. While traditional bearing−based isolation reduces seismic responses by introducing a flexible isolation layer, it ...

Symmetry Breaking Metamaterial Sleeve Actuators

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 11, November 2025.
Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.
