Coastal bridge piers suffer random performance deterioration owing to the presence of complex nonuniform corrosion characteristics and material uncertainties. Some these will also be threatened by earthquakes during a long-term service period, therefore, structural safety needs probabilistically assessed seismic reliability method. To deal with this problem, we present method calculate time-dependent coastal pier, comprehensively considering randomness event, corrosion, uncertainty. First,...
The degradation of seismic performance for RC bridge piers induced by chloride corrosion has previously been studied treating the earthquake as a unilateral cyclic loading. Such studies do not consider true response pier under joint effect damage and real multi-dimensional action. Thus, in present study, behavior rectangular subjected to coupling effects bidirectional loading was numerically investigated. First, corrosion-induced deterioration material mechanical properties is introduced....
Abstract Herein, an all‐solid‐state sequential self‐organization and self‐assembly process is reported for the in situ construction of a color tunable luminous inorganic/polymer hybrid with high direct piezoresponse. The primary inorganic solid polymer subsequent are achieved at pressure first utilization piezo‐copolymer (PVDF‐TrFE) as host matrix guest carbon quantum dots (CQDs). This induces spontaneous formation highly ordered, microscale, polygonal, hierarchically structured...
Polyhydroxybutyrate (PHB) with special wrinkled spherulites enables significant improvement in triboelectric outputs of the microbial polyester.
Nowadays, wearable and flexible nanogenerators are of great importance for portable personal electronics. A piezoelectric energy harvester (f-PEH) based on Bi3.15Nd0.85Ti3O12 single crystalline nanoplates (BNdT NPs) polydimethylsiloxane (PDMS) elastomeric polymer was fabricated, high harvesting performance achieved. The output is highly dependent the mass ratio BNdT NPs in PDMS matrix. as-prepared f-PEH with 12.5 wt% presents highest voltage 10 V, a peak-peak short-circuit current 1 μA,...
The present study demonstrates for the first time incredible potential of earth abundant silicon based quantum dots flexible, multi-functional, and self-powered optoelectronics.
The pressboard surface is the electric weak link of oil-paper insulation in transformers, and long-term partial discharge (PD) erosion dominant cause degradation pressboard. To explore development processes tracking under effect tip curvature, typical needle-plate model was selected to initiate an field with a high tangential component on needle curvature 4~42 μm. With help high-speed camera PD detecting system, were recorded sustained AC voltage. A profound difference between different...
In order to realize an online power supply, this article develops explicit design of induction extraction technology combined with wireless transmission (WPT) technology. Unlike the supply mode traditional batteries monitoring devices high-voltage lines, solves short battery life cycle problems. First, principle is analyzed. Based on equivalent circuit mutual inductance model, expressions without and core saturation are derived, respectively. According current transformer (CT) magnetic...
A hydrophilic and hierarchical 3D stereocomplexed crystalline meshwork was <italic>in situ</italic> constructed in fully bio-derived enantiomeric polylactide/cellulose nanocrystal nanocomposites.
This study explores the influence of hydrostatic pressure on discharge along oil-paper interface under AC voltage, especially for normal operating condition and breakdown. In this paper, an experimental platform was set up to record partial (PD) parameters test sample different pressures, while applied voltage increased final flashover step by step. Experimental results showed that higher had effects PD voltages. Higher decreased energy voltage. Furthermore, pressure, traces (white mark)...
The main dielectric medium in converter transformers is the oil-pressboard. valve windings of are subjected to AC-DC combined voltage. Creepage discharge a common defect oil-pressboard insulation. degree oil-immersed pressboard (OIP) damage directly affected by different creepage paths. In this study, needle-plate model was developed explore paths insulation under A high-speed camera used record developmental process white marks on OIP. We explored reasons behind voltage types. Results...
The phenomena of white marks on the pressboard could reduce performance oil-paper composite insulation, which is accessed scrapped transformers. Whereas it much difficult to find during overhaul power ac transformer because mark channel generally disappear when connected air. So important a method detect pressboard. At first, throughout understanding development process should carry out under laboratory condition. A typical needle-plate electrodes model with was selected initiate divergent...
