To improve the performance of vehicle suspension, this paper proposes a semi-active suspension with magnetorheological fluid (MRF) damper. We designed an optimized fuzzy skyhook controller grey wolf optimizer (GWO) algorithm base on new neuro-inverse model MRF Because inverse damper is difficult to establish directly, Elman neural network was applied. The novelty study application for vibration control and optimization method. calculation results showed that can accurately calculate required...
The characterization of delamination in composite plates with ultrasonic waves generated and detected by lasers is presented. Composite materials have become one the most important structural aviation industry because their excellent mechanical properties, such as high specific stiffness antifatigue. This paper reports a new application laser technique to perform nondestructive detection carbon-fiber-reinforced plastic (CFRP) continuous-fiber-reinforced ceramic matrix composites (CFCCs)...
Benzene-induced erythropoietic depression has been proposed to be due the production of toxic metabolites. Presently, cytotoxicities benzene metabolites, including phenol, catechol, hydroquinone, and 1,2,4-benzenetriol, erythroid progenitor-like K562 cells were investigated. After exposure these showed significant inhibition viability apoptotic characteristics. Each metabolite caused a increase in activities caspase-3, -8, -9, pretreatment with -9 inhibitors significantly inhibited...
Abstract SARS-CoV-2 unprecedentedly threatens the public health at worldwide level. There is an urgent need to develop effective vaccine within a highly accelerated time. Here, we present most comprehensive S-protein-based linear B-cell epitope candidate list by combining epitopes predicted eight widely-used immune-informatics methods with curated from literature published between Feb 6, 2020 and July 10, 2020. We find four top prioritized in hotspot regions of S protein can specifically...
Multi-operation within a field and multi-machinery machinery operation are common in the scene of scaled farm service, especially with soaring usage automated steering system small medium cooperatives. The object this study was to explore precise efficient in-field coordination method realize flow-shop scheduling for fleet equipped RTK-GNSS based auto-steering system. new is on three-dimensional coordinate (XYZ), which concept field, strip, task were defined. Under framework, strip state...
Sodium sulfate (Na2SO4) and sodium carbonate (Na2CO3) are weakly alkaline activators. Alkali-activated slag (AAS) cement prepared from them shows special advantage in long setting time low shrinkage, but it also slow development of mechanical properties. In this paper, Na2SO4 Na2CO3 were used as activator compounded with reactive magnesium oxide (MgO) calcium hydroxide (Ca(OH)2) to optimize the The hydration products microscopic morphology studied by XRD, SEM EDS, production cost...
A non-Newton fluid microvibration isolator is studied in this paper and several nonlinear models are firstly presented to characterize its vibration behaviors due the complicated effects of internal structure, external excitation, property. On basis testing hysteretic loops, generalized pattern search (GPS) algorithm MATLAB optimization toolbox used identify model parameters. With use fourth-order Runge-Kutta method, performance these further estimated. The results show that, cases force...
Vibration isolation is an important method of spacecraft vibration control, and the study performance theoretical basis to design isolators analyze transmissibility characteristics. This paper mainly studies a type fluid microvibration new nonlinear three-parameter model first constructed in which pth power damping qth stiffness are placed series. With application harmonic balance (HBM), force absolute displacement curves under different parameters obtained. Then based on self-defined...
As a typical flow element in an aero-engines, orifices play vital role the distribution and control of mass rate within secondary air system. In particular, rotating with complex geometry (Euler angles) may significantly vary discharge coefficients. Understanding coefficients these guarantee more reasonable internal This contributes to safety, reliability, structural integrity aero-engine under all-inclusive line. this paper, state orifice coefficient have been studied condition different...
The current train model of the control system is unable to accurately reflect influence nonlinear running resistance, line conditions, mutative mass value, and external environment changes on in dynamics, resulting a defect poor performance. basic additional resistances are discussed this paper, novel neural network online learning method time-varying dynamic proposed, combined with characteristics rail transit lines, algorithm designed by categories steps. This can identify value that...
The mechanical wave is emphases and difficult content in physical university course.Using the plane simple harmonic as an example, meaning of equation clarified; phase difference between two particles medium coherent sources also discussed.Analyzed simulated process superposition with software Matlab this paper to help students understand digest part content.
