To improve the quality of hydroentangled nonwoven cotton fiber web and optimize parameters hydroentanglement, hydroentanglement process was simulated using a finite-element method. A established based on fractal principle. In this work, model developed LS-DYNA software. The effects water jet pressure distance thickness were investigated model. relevant experiment designed to verify effectiveness Computer simulations experiments show that higher shorter will decrease thickness. results there...
Porosity is one of the most important properties textile materials that ensures their comfort and usability. The internal pore structure cotton fiber assembly complex changeable, surface difficult to explain its structure. It intended develop a method predict morphology assembly. Pore image multi-layer collected by photography instrument, used Image Pro Plus 6.0 software analyze, obtained white area indicators which can be applied describe void space Using multiple linear regression analysis...
When a water drop is placed on hot solid surface, it either undergoes explosive contact boiling or exhibits stable state. In the latter case, floats over an insulating layer of vapor generated by rapid vaporization at surface/drop interface; this known as Leidenfrost Here, we discuss previously unrecognized steady state in which “stands” smooth surface. state, stabilizes itself with partial adhesion leading to unique deformation and rotation behavior reminiscent Sufi whirling—a form spinning...
In order to improve the package quality of nonwoven and reduce defects in production process, tension fluctuation winding process is studied. A device built nonwoven, measured data obtained. The characteristic analyzed, different simulation curves have been set. Under curves, corresponding stress distribution calculated, influence on analyzed. Accordingly, a fuzzy proportional integral differential (PID) control strategy proposed optimize product quality. Matlab establishes PID models,...
To analyze the stress state of seed cotton in process ginning and to improve quality lint, a new model for cotton, laminated model, is presented based on idea composite laminate. The assumes mass made up certain number fibers, each which has different arrangement angle. Based this simulated using finite element analysis. mechanical properties single fiber that either machine- or hand-picked are obtained. working condition described successfully. By analyzing influence conditions serration...
For embankment dams over 150 m in height, there is a strong tensile effect on the core near bank slope under action of water storage. The cracking due to tension can threaten overall safety dam. Therefore, it very crucial perform reliability analysis crack resistance high asphalt core. In this study, considered basis failure. Taking ultimate strain as control index, calculation method established for dam based mixed-level uniform design (MLUD) and response surface (RSM). Considering...
In order to analyze the mesoscopic contact characteristics of cotton fiber creep, this paper uses meso-particle discrete element method establish a assembly creep microscopic model based on existing experiment. The parameters Particle Flow Code constitutive are calibrated according macroscopic mechanical indexes obtained from experiments, and strain in instantaneous stage under different compressive stresses force between particles analyzed. According time–temperature equivalence principle,...
During winding, the defects of wrinkles and buckling are prone to occur in material package. This problem increases larger packaging sizes, it is related uneven distribution internal stress. In order study stress law wound package, necessary analyze discuss mechanical behavior winding process. this paper, a model based on thick-cylinder theory was established deduce change Polypropylene melt-blown nonwoven fabric used as test material; showed no deformation residue after stretching test,...
Abstract Combined with Laplace transform and creep stress conditions, an accurate expression of the viscoelastic Poisson's ratio calculated from transverse strain relax modulus is derived. From tests data, Prony series nonwovens time were obtained, time-varying curve was simulated by 1stOpt software. The method proposed can effectively obtain provide a reference value for calculating mechanical indexes involved in its subsequent production processing.
For CSNS RCS tune measurement, value is measured by exciting the bunch with a strip-line kicker fed white noise and using FFT algorithm. This article simulates in efficiency of discussed Matlab environment. The parameters an arc electrode structure such as VSWR, wake impedance, thermal state are analyzed based on advantages this design.
To analyze the relationship between tension force of a rope and bundled material's indentation, model tightening by for soft material was designed testing. By calculating indentation depth materials from stretching displacement, variation law with different mechanical properties ropes analyzed. As progresses, more winding turns, shallower depth. The friction coefficient does not significantly affect theoretical high-strength shows linear pattern. high-extension is negative. With ordinary...
