Characteristics of Vibration and Sound Radiation of Metro Resilient Wheel

open access: yesChinese Journal of Mechanical Engineering, 2019
Resilient wheels are extensively used in urban rail transit, especially for tramway systems, owing to its advantages in noise reduction. A new type of resilient wheel for a metro is designed, and its characteristics of vibration and sound radiation ...

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Research on New Cutting-type Anti-climbers for Urban Rail Transit Vehicles

open access: yesChengshi guidao jiaotong yanjiu
[Objective] Currently, the CAC (cutting-type anti-climber) faces the issue of excessively high initial peak cutting force, leading to cutting tool detachment or fracture and finally the anti-climber failure.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

open access: yesAdvanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
