| Popis: | This paper devoted computer modelling of wind impacts on the silos for grain storage in order to obtain their aerodynamic characteristics. This modelling was made in the system of computer analysis Ansys Workbench for various wind conditions and different layouts of silos: separately located silo and silo parks by varying their sizes and mutual arrangement at various angles of the wind pressure. Within the numerical experiment it was obtained not only a huge array of data about the aerodynamic resistance of the silos, but also developed a special technique of the mathematical modelling of the wind effects on the selected class of constructions. This technique is a single software module for the platform Ansys Workbench, which automatically forms an optimal calculation area, makes an estimation of the wind loads on the silo and exports obtained loads in the software package SCAD for calculating the strength and deformability. To achieve this goal it was made the calculation of the same tasks on meshes of different dimensions, set the dimensions of the mesh in different places of the calculation area and installed the minimum required time of computer simulations. |
