Optimization of bias modification and dynamic behavior analysis of helical gear system
Advances in Mechanical Engineering, 2017 A generalized finite element dynamic model of helical gear system considering time-varying mesh stiffness and loaded composite mesh error is developed. Bias modification is introduced into this model, and the corresponding time-varying mesh stiffness and

Bifurcation phenomena in internal dynamics of gear systems [PDF]
Applied and Computational Mechanics, 2007 The impact effects in gear mesh represent specific phenomena in the dynamic investigation of highspeed light transmission systems with kinematic couplings. They are caused of greater dynamic than static elastic deformations in meshing gear profiles.

Advanced Functional Materials, EarlyView.Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Advanced Functional Materials, EarlyView.A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).

Advanced Functional Materials, EarlyView.Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.
