MAGNETORHEOLOGICAL ELASTOMER-BASED FLEXIBLE COUPLING FOR TORSIONAL VIBRATION ISOLATION

, 2022
Employing vibration isolation can avoid the detrimental effects of unattenuated torsional vibrations on rotary mechanical equipment. Semi-active vibration isolators can effectively reduce the vibration levels in mechanical systems. Magnetorheological elastomers (MREs) are a class of smart materials whose mechanical and rheological properties can be ...

Data‐Driven Printability Modeling of Hydrogels for Precise Direct Ink Writing Based on Rheological Properties

Advanced Science, EarlyView.
A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...
