Dynamic Features of Non-Return Mechanism in Hatch Door of Amphibious Aircraft
Aerospace, 2023 The non-return mechanism is the key device that plays the role of braking in the opening-and-closing electric actuator of an amphibious aircraft hatch door. The ball-and-socket contact pair, providing the pressing force, and the multi-disc friction pair,

Matrix Stiffness Governs Fibroblasts’ Regulation of Gingival Immune Homeostasis
Advanced Materials, EarlyView.This study identifies a “mechano‐epigenetic” checkpoint in which matrix stiffness governs the immune responses of gingival fibroblasts. Using biomimetic hydrogels and human gingival explants, the studies revealed that restoring extracellular matrix stiffness actively suppresses inflammation via non‐canonical NF‐κB signaling and DNA methylation ...

Advanced Robotics Research, EarlyView.This study introduces a hybrid robot that integrates mechanical assistance by musculoskeletons (i.e., soft pneumatic muscle with rigid exoskeletal extensions), neuromuscular electrical stimulation, and vibrotactile feedback in a lightweight wearable mechatronic complex applicable to the paretic ankle–foot poststroke for gait restoration. The system can

Effect of Frictional Force Distribution on Exciting Force of Brake Noise for Motorcycle Disk Brake
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2006 This paper presents the results of experiment and analysis from view of structural mechanics for brake noise that is serious problem of motorcycle. Some brake bench tests were conducted to some cases of friction force distribution, and it was found that the cause of brake noise was stick-slip effect between brake disk and pads.
