A grooved texture surface was fabricated to enhance the wear resistance of guide rail molding machine. The effects sand concentration in oil and groove width on tribological properties were studied using a pin-on-disk tribometer. Surfaces with widths 1000 μm (S1) 1500 (S2) had lower friction coefficient better anti-wear than non-grooved textured (S0) when lubricated 0% 5% sand–oil mixture. However, rate S1 S2 higher those S0 increased 10%. enhanced under low because grooves captured particle...
Abstract In this study, composite coatings of polyvinylidene fluoride (PVDF) and epoxy resin deposited with La2O3 MoS2 nanoparticles on the surface a Babbitt alloy have been studied in order to improve its tribological performance. A pin-on-disc tribometer was used evaluate properties alloys without coatings. The results showed that compared polymer-La2O3 coating, polymer-MoS2 coating more effective reducing friction coefficient wear rate substrate under both dry boundary lubrication...
This article presents the preparation of Kevlar aramid fiber (AF) braided fabric/epoxy resin (EP) composite laminates through plasma treatment and a hand-folding process. The electrical mechanical properties these are compared analyzed. modified AF cloth is examined using scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR). results confirm an increase in number C <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
In this study, a cladding layer and nitriding were prepared on nodular cast iron, to provide guidance for remanufacturing of iron. Their microstructure composition the tribological properties under dry starved lubrication conditions studied. Meanwhile, contact stresses at different friction stages simulated through finite element method. The micro-hardness 694 HV0.5 724.5 HV0.5, which 4 times 4.2 higher than that substrate. For conditions, wear resistance 113.2 65.5 coefficients lower...
By far there is lack of research on different working conditions between rigid and flexible dynamics truck mounted concrete pump booms. First a 3D model has been established by using virtual prototyping technology 37 m long boom in Pro/Engineering software. Then the body simulation built. Next modal superimposition method adopted to change 4 booms into ones. Kinematics law dynamic characteristics common had studied then. tip displacement first hydraulic cylinder force models have researched....
The paper determines the impact factors of dynamics a motorized spindle rotor system due to high speed: centrifugal force and bearing stiffness softening. A nonlinear dynamic model grinding considering above is constructed. Through simulation including phase portraits Poincaré map, periodic behavior chaotic are revealed. threshold curve chaos motion obtained through Melnikov method. conclusion can provide theoretical basis for researching deeply behaviors system.

Sidewall roughness is a key factor influencing the shaft resistance of rock-socketed piles. Owing to difficulties in onsite measuring and inconsistency quantitatively characterizing degree sidewalls, existing approaches for estimating piles often cannot take this into account. Based on measured surface curves 68 sockets No. 6# 7# group Chishi Bridge Ru-Chen Expressway China, sidewall described by introducing (RF) based Horvath Monash models, respectively, while statistical analysis sections...
Abstract Recently, the synergistic tribological properties between molybdenum dialkyldithiocarbamate (MoDTC) and metal detergents have been focus of significant attention due to high requirements engine oil. In this study, an SRV tribometer four-ball machine were used study performance MoDTC combined with three types different base numbers. Meanwhile, detergency was also investigated using hot tube test crankcase simulation test. The results showed that (i) a high-based detergent possessed...
Abstract This paper presents an algorithm for identifying the process parameters of a laminated plate reinforcement mesh. To accommodate actual production needs, computer software line is employed identification and data processing DXF steel mesh file. In this context, C++ programming utilized imported file, as per line’s requirements. AutoCAD vector graphics exchange file that available in two storage formats: ASCII format binary format. The easily readable therefore, widely used, with most...
In order to reduce carbon emissions and realize the dual-carbon strategy, it is particularly important reasonably predict demand of electric power load achieve a high degree fit between supply side user side. Aiming at problem low accuracy fluctuation regional long time series prediction, this paper proposes combination whale algorithm optimization, VMD, Informer prediction model. Firstly, optimization used select optimize parameters so as obtain more stable VMD parameters. Then decompose...
