A Study on Stoma Arrangement of Air-Cushion Lamination and Numerical Simulation of the Pressure Field

Cushion has a wide range of applications in engineering. It is a new attempt to use it in the field of printing and packaging lamination process, to get a numerical simulation study analyzes for the distribution of the formation pressure of the air cushion pressure chamber. On the basis of analysis of the principle of air-cushion laminated device, make it clear for the requirements of the air cushion pressure distribution, pressure distribution from a single stomatal mathematical model, using ANSYS finite element software, numerical simulation of multi-stoma pressure distribution. The results showed that: stomata arranged in the form of cushion thickness, stomatal spacing and stomatal row spacing uniformity of the distribution greater impact on the cushion pressure; small stomatal spacing and stomatal row spacing will help improve the air cushion pressure distribution uniformity; reasonable cushion thickness stomatal spacing and stomatal row spacing, the selected diameter of the pores smaller cushion pressure distribution uniformity.
