Abstract In this paper, a novel resonant pressure sensor is developed based on electrostatic excitation and piezoresistive detection. The measured applied to the diaphragm will cause frequency shift of resonator. working mode stress–frequency theory double-ended tuning fork with an enhanced coupling beam proposed, which compatible simulation experiment. A unique detection method small axially deformed beams status other adjacent outputs are easily shielded. According structure design,...
Abstract A high-accuracy differential resonant pressure sensor with two similar resonators is proposed using the linear fitting method to guarantee its output linearity without polynomial compensation. Results reveal that nonlinearity of largely dependent on tensile/compressive pressure–stress ratio c when are used separately as compressive and tensile elements. Nonlinearity decreases sharply an appropriate . theoretical model obtain minimal shows satisfactory agreement simulation results....
The bridge discussed in this article is the first super-long of Zheng-Wan high-speed railway project to span main channel South-to-North Water Diversion Project China. a 160 m beam–arch composite structure with concrete-filled steel tubes. To ensure water quality safety, construction method beam and then arch was adopted, which tube ribs were constructed by vertical rotation. monitoring rotation conducted numerical analysis clarify strength stability tower ribs, evaluate safety support local...
The fuzzy cluster analysis for monitoring data, based on SOM neural network, was applied to study the working behaviors of transverse joints super arch dam during construction phase. parental samples were identified with classification results fuzzy-cluster researches. Thereby, Elman network used diagnose test samples. Introducing data from as an example, show that proposed method has superb applicability and stability in both error diagnosis accuracy.
This article analyze the slope stability by strength reduction method named Phi-c which supplied FE software PLAXIS. The factor is suggest to be safety of at moment when reaches instability, numerical non-convergence occurs simultaneously. position sliding surface and dynamic simulation instability can obtain as well. has compared results calculated other methods Bishop ABAQUS with difference between 2%-3% attest its accuracy practicability in engineering.
