In this study, a large thrust linear ultrasonic motor using an L-shaped stator is described. The constructed by two mutually perpendicular rectangular plate vibrators, one of which mounted in parallel with the slider to make structure be more compact. symmetric and antisymmetric modes based on first order bending vibration vibrators are adopted, each resonance mode assigned drive direction. placement piezoelectric ceramics could determined finite element analysis, influence slots head block...
To reduce the conventional energy consumption in rural area of China, tobacco stems briquetting (TSB) was used as fuel during process flue-curing, compared with honeycomb briquette (HB). Three fire furnaces different heat exchangers using TSB were flue-curing. The results showed that smog temperature higher than HB, efficiency bio-fuel system from 43.5% to 54%, while traditional 51.5%. And cost flue-curing per hectare and HB $750.0 $1282.5, respectively. It is proved an alternative choice...
In order to meet the demand of a linear ultrasonic motor with large thrust in narrow space, novel Π-type double driving feet is proposed. this paper, structure stator designed. The working mode and size are determined by finite element simulation. To amplify amplitude foot, an optimization design for performed. After that, pre-load device that separates from put forward, which can not only improve output but also help operation stability prolong life motor. Additionally, prototype proposed...
A point contact model is developed to analyze the fundamental characteristics of a single-mode actuation type linear piezoelectric actuator in this paper. The prototype plate using two-phase excitation, which realizes bi-directional motion by changing vibration mode within different exciting frequencies. Differs from other models, barycenter stator taken into account, and trajectories driving tip are simulated measured with without consideration mechanical contact. results show that spiral...
The influences of different vermicompost concentrations 8.33, 4.35 and 0.9%, respectively (based on TS), the CH4 production, Specific Methanogenic Activities (SMAs) anaerobic sludge, pH COD removal were investigated. A maximum cumulative production 874 ml/L fermentation liquor was obtained from experiment with concentration 8.33% which increased by 40.3% when compared control, a SMA 295.9 mg CH4/g VS•d achieved 45% relative to control. results also showed that could enhance improve buffering...
The transesterification reaction of beef tallow to biodiesel using Cs <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> O/γ-Al O xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> as a solid base catalyst was studied. Response surface methodology and central composite rotation design were employed optimize the conditions. optimum conditions giving 95.5% yield were: time 120 min, temperature 66°C, amount 5.3% (based on weight oil), molar...
During the combustion of straw, formation deposits, which erode heating surface furnace and affects safe operation, is influenced by many factors. This paper studies influences straw shape on deposit formation. The result as follows. fuel process combustion, accordingly, it law properties deposits. Firstly, change deposition rate different from native straw; secondly, amount are significantly lower than that produced at last, has an important influence characteristics component deposit.
The low bulk density of straw is one the major barriers, which blocks collection, handling, transportation and storage. Densification biomass into briquettes/pellets a suitable method increasing biomass. Yet in process, tremendous amount air ejected from grind, brings substantial specific variation including combustion property. Among them, property critical for proper design operation burning facilities. Therefore, series tests about properties 75mm diameter corn briquettes were done....
The possibility of vermicompost enhancing methane production as additive was evaluated by anaerobic batch digestion experiments synthetic wastewater. effects different concentrations, on the base TS, 10%, 5%, 1% wastewater mass respectively, and process were investigated at constant amount inoculated sludge. Each experiment successively conducted twice under mesophilic conditions. results show that could increase 25.2% most relative to control specific methanogenic activity sludge, it also...
