Abstract The optimal design of hydraulic fracturing parameters is the key to commercial exploitation unconventional reservoirs. Hydraulic test one main methods for optimizing parameters. It known that scale effect exists between laboratory experiments and field treatments fracturing. However, studies on how eliminate are rarely reported. In this work, we conduct sensitivity analysis rock mechanical at different scales by using dimensionless method. initiation propagation process reproduced...
Fracture characterization is essential for estimating the stimulated reservoir volume and guiding subsequent hydraulic fracturing stimulations in shale reservoirs. Laboratory experiments can help provide theoretical technical guidance field operations. In this study, on samples from Niutitang Formation Hunan Province (China) under a uniaxial loading condition are conducted. The multifractal method used to analyze acoustic emission (AE) signals characterize fracture initiation propagation....
Due to the strong magnetic force between segments of permanent magnet guideway (PMG), unmovable electromagnetic turnout becomes one most possible choices for high-temperature superconducting (HTS) maglev systems. Meanwhile, it has advantages quicker response and smaller volume compared with mechanical turnout. A complete system is vital further evaluating feasibility. Based on previous studies in ASCLab Southwest Jiaotong University, a prototype introduced this article, which consists two...
For lack of structure rigidity foundation and radial force diminishing exponentially with the distance gland, a newly packing sealing opening hollow metal ring supporting is designed. Through finite element analysis, it comes out that disadvantages are divided adding effect high pressure resistant. The increased,preload reduced , mechanical seals can be replaced under certain condition.
A rich spectrum of slip behaviors, spanning from aseismic creep (mm/yr) to seismic (m/s), has been observed in many subduction zones and some strike-slip faults. Slow earthquakes, intermediate between these two end-member modes, exhibit transitional behaviors fault sections adjacent the seismogenic zone. Focusing on zones, it is shown that they experience deformation not only along discrete planes but also over distributed frictional-viscous shear latter which are thought be responsible for...
Piezoresistive micro-mechanical acceleration sensor is one of the earliest developed silicon sensors in MEMS. Its cantilever beam main component. So structure optimization design becomes key. During process former beam, working way between program FEM analysis and optimizes belong to a kind series connection, so we must interface order realize data transmit optimize program. This paper tries replace with neural network carries on piezoresistive sensor, can be interpreted as relation...
Three-point bending stress analysis was carried out on the model using ANSYS software. The single factor method used to study influence of different factors and strain interconnection solder joint under three-point load.Use SAC305 as material. A QFN materials out.With gap height, length width joints design variables, value target value, 15 groups models with levels combinations were designed response surface method, corresponding values obtained. regression equations welding spot structural...
Abstract Calculate the joint connection spring rigidity of prefabricated low multi-story villa according to relevant specification and take modeling analysis by using SAP2000 finite element software. Respectively analyze elastic-plastic time-history under moderate earthquakes major earthquakes, checking calculation structural safety obtain conclusion support project complete smoothly so as provide design basis for this kind prefabricatedvilla.
The finite element analysis model of board-level circuit module solder joints is established, and the torsional load applied to stress simulation analysis. It found that maximum point appears on QFP joint. joint research object, height, length thickness are design variables. Taking value under torsion as target value, 17 sets models with different levels combination were designed by response surface method corresponding was obtained. A regression equation established using relationship...
The technology of autonomous vehicles is growing fast in current time.On one hand, the popularization expected to greatly reduce occurrence traffic accidents, meanwhile lowers income premium for insurance companies; on other decrease accidents also reduces amount claim these companies.Based actuarial model manual and data vehicles, this paper proposes an then computes corresponding premium.Through comparison between premiums we find that not only financial burden their owners, but cost...
