This paper is devoted to the mathematical and computer simulation of multi-parameter systems. We show that the method and algorithm can easily be used in nonlinear net simulation of the systems. Simulation is based on experimental data and achieved by the variation of one-dimensional spline approximations. A set of variable one-dimensional splines is the result of simulation. Each of the splines is the image of a section of input parameters area. Software realization is based on the single algorithm that is used repeatedly. The method have been used in investigation some technological conditions of laminating fabrics systems. Specifically, we investigated the stability of gluing joints, hardness and bending of various parts of clothes. Also, we got the simulator of constituent elements of the mixture which may be used in label products as a temperature indicator. The examples eventually demonstrate the efficiency of the presented method.
Abstract. The electronics development demands for accuracy of printed technologies, in particular, to screen printing. Under a flat blade operation the print form is deformed and the image is distorted relative to the original. A squeegee in a form of a smooth cylinder reduces distortion, but it allows obtaining satisfactory print quality only when using high density grids. The paper shows findings of using roller squeegee with dosed ink supply. The roller squeegee is provided with an elastic layer. Dosage is carried out due to the cells on the elastic layer surface. There were used meshes 100-31 and 120-34 for the stencil. The experiments were carried out with layers of photopolymers and rubber. The carried out calculations made possible to choose the optimum printing pressure. Under the selected conditions, the printed image had minimal distortion. The findings allow drawing a conclusion about the possibility of roller squeegee using in chips manufacture according to LTCC-technology.
This paper is devoted to the mathematical calculation and experimental researching of ink apparatus using in printing machines. We show the existence of structuring process in ink boxes and the formation of so-called quasi-solid in the printing ink. Our geometric model is based on the mathematical problem of covering some planar domains by the set of circles. All circles belong to one-parameter family and it is a special feature of the problem. Using this model we get the method of calculation some optimal dimensions of passive activators using for destruction the quasi-solid. Calculations are based on experimental data and it is achieved by variation of several parameters. In this paper we describe the system with only one passive activator but there exist the opportunity to optimize the system with several ones. Software realization is not given in the paper but it is based on the algorithms that are described. Experimental data were received with using real equipments and materials of printing industry. Specifically, we investigated the generating of quasi-solids in the ink boxes and we got some results for using the passive activators.
