The lubricating layer modelling and simulating at band dressing
The presented animated film consists of five parts: 1. Technological scheme on banddressing is shown, 3D presentation of the process, applying O.Reynold's differential equation, surface roughness of the band and rollers, Gauss's law of distribution and Fouriers series. 2. Calculations of the lubricating layer at the input crosscut of deformation area are given for the smooth surface of the rollers and transverse band roughness. The output results are modelled for the case of insufficiently wetted surfaces. 3. In the calculation, the roughness of rollers, which is congruent along the analysed band profile, is also taken into account. Solutions got by Monte-Carlo numerical method are modelled in the same way as in Part 2. 4. The lubricating layer, when the roughness if rollers is linearly moved by 1/4 of the band profile, is modelled. Targeted pictures of mathematical calculations aimed at disclosing 'islands of stability' and 'saddes of stability' of the grasing layer are given. The results got are compared to the results in Part 3. 5. The surface band roughness in relation to smooth surfaces of rollers is simulated by two functions: a) In the exponent of natural logarithm is the sine function b) Band roughness is simulated by the irrational function
