Selection of factors and preparation of an experiment planning matrix for modeling a filter material with an orthotropic structure based on woven meshes

Abstract

The advantages of a filtering material with an orthotropic structure (FMTS) consisting of a package of woven meshes are described. Information is given on the first stage of FMTS modeling, which includes the choice of parameters and factors of the experiment and the compilation of a planning matrix to establish the relationship between technological characteristics and properties of FMTS. When constructing a stochastic mathematical model at this stage, two factors were chosen to describe the properties of the material – qualitative (mesh type), specified by the sigma constraint method, and quantitative (package thickness). The constructed matrix of experiment planning is given. The natural and coded values of FMTS samples were determined.

Research of the possibility of using filter materials with orthotropic structure based on woven nets for cleaning diesel fuel

“…At the moment, a fairly large amount of work has been done in the FMTS development: promising designs of filter materials with an orthotropic structure based on woven meshes have been described, a material model has been developed with a simple regular structure (or FMTS with a simple laying of meshes, when mesh layers are stacked on top of each other in the same spatial orientation), on the basis of which equations were developed for calculating the structural and hydrodynamic properties [3]; the possibilities of using 3-D modeling and 3-D printing to study the properties of FMTS, in particular, with the structure described above, are disclosed, which can significantly reduce the complexity of the research process [4,5]; on the basis of FMTS, a filter for coarse cleaning of herbicides and a drainage element for the catalytic treatment unit in a water deironing plant were developed, manufactured and implemented [3,6]; a systematic approach has been developed for compiling an experiment planning matrix to establish the relationship between technological characteristics and FMTS properties [7].…”
