Flexible sensors with wide sensing ranges require responsiveness under tiny and large strains. However, the development of strain detection is still a great challenge due to conflict between requirements sparse conductive networks requirement dense networks. Herein, we present facile method for fabricating gradient network composed The surface penetration technology in which carbon black (CB) penetrated from natural rubber latex (NRL) glove interior was used fabricate network. prolonged...
The commercial blue persistent luminescent (PersL) phosphor (CaAl2O4:Eu2+,Nd3+) is renowned for its exceptional PersL duration, but it hampered by poor chemical stability. There an urgent need to develop phosphors that can combine the excellent property with robust In this work, we report on a series of highly stable Ce3+-doped oxynitride phosphors. Notably, BaSi3Al3O4N5:Ce3+ has been identified contain two distinct types defects in host: one associated photoluminescence (PL) and other...
Eccentricity is a common failure of rotor systems in actual engineering such as disk-drum structures. This work aims to explore the coupling vibration system considering eccentricity effect. Firstly, artificial spring method was utilized express bolted joint condition with an eccentricity. Then, rotational effect, new dynamic model flexible proposed. The correctness verified using experiment. frequency curves and mode shapes were used discuss behaviors eccentric or without rotation,...
The influence of shaft bending on the coupling vibration rotor‐blades system is nonignorable. Therefore, this paper analyzed system. mode function under elastic supporting condition was also derived to ensure accuracy model as well. number blades, position disk, and support stiffness critical speed analyzed. numerical results show that there were two categories shapes which belong a set where blade’s first modes predominate in system: shaft‐blade (SB) interblade (BB) due between blade shaft....
Forced vibration of thin-wall cylindrical shell under nonlinear boundary condition was discussed in this paper. The modeled as supported clearance one end and the restraint assumed linearly elastic radial direction. Based on Sanders’ theory, Lagrange equation utilized to derive governing equations shell. displacements three directions were represented by beam functions trigonometric functions. In study dynamic responses with external loads, Newmark method is used obtain time history,...
Consideration is given to dynamic behavior of cylindrical pressure pipe with elastic boundary conditions. Based on Sanders’ shell theory and Hamilton principle, the system equations are established for integrating uniform distributed into condition. In analytical formulation, Rayleigh–Ritz method a set displacement shape functions used deduce mass, damping, stiffness matrices system. The displacements in three directions represented by characteristic orthogonal polynomial series...
Based on the analysis crushing process and hysteresis of material layers, a hysteretic model with symmetrical clearances is presented. The mechanical two-degree freedom bilinear its dynamical equations system are proposed. In order to further investigate dynamic characteristics novel vibratory cone crusher, also simplified into single degree component together clearances. According some nonlinear tools such as bifurcation diagram, Lyapunov exponents, Poincare section, etc., different motion...
In this paper, the experimental setup of a pendulum with moving mass is established to study rapid suppression oscillation. The intermittent motion employed achieve more efficient suppression. proposed control method can reduce distance rapidly in vicinity vertical position ensure stability system. triggered by recognizing angle real time so that nonsynchronous be avoided. With verification accuracy controlled distance, effects several parameters are studied. Moreover, results reveal...
