Experimental investigation on the dynamic characteristics and transverse vibration instabilities of transmission belts [PDF]
, 2008 Serpentine belt drives are often used in front end accessory drive of automotive engine. Dynamic characteristics of belts play an important role in the behavior of such transmission and are inputs of simulation software. Moreover, free belt spans exhibit

Advanced Science, EarlyView.Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices
Advanced Science, EarlyView.This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

Flutter of Darrieus wind turbine blades [PDF]
The testing of Darrieus wind turbines has indicated that under certain conditions, serious vibrations of the blades can occur, involving flatwise bending, torsion, and chordwise bending. A theoretical method of predicting the aeroelastic stability of the

Advanced Science, EarlyView.By grafting dense long double‐brush chains, we synthesized bottlebrush networks with high theoretical enthalpy. Their low entanglement, combined with dynamic bonds, promotes crystalline domain reorganization and minimizes enthalpy loss, achieving a record enthalpy of 240.7 J·g−1.
