| Title of the article | Assessment of the bearing capacity of the cylindrical diffuser |
| Abstract. | The article reviews the assessment of a load-bearing capacity of an existing cylindrical diffuser with a length of 46 m and diameter 5,6 m. The main aspect of that kind of calculations is a creation of a finite element model of the diffuser. Models were made in different software such us «Lira» and «Ansys». The peculiarities of this process were in correct modeling of openings in the shell of the diffuser and using of shell finite elements instead of 3D-elements. The combined work of a shell of the diffuser with the lids over the openings achieved with 38 bolts allocated along perimeter of the openings. This lid-openings system was modeled separately from diffuser for the establishing of a real strain-stress state of that system. Model was made with 3D finite elements and included lid, part of the shell and bolts. The significant influence on the strain-stress state of that system was also provided by the value of pretension in the bolts. The more pretension was induced in bolts the more combined work was provided in the lid-openings system. Real strain-stress state of the system showed an increase in stress up to 2,6 times. |
