MARTINEZ-HERNANDEZ, Carlos M.; MENDEZ-GOMEZ, Leandro  and  FLORES-RUIZ, José. Analysis of Von Mises Tense in Anaerobic Biodigesters Type Rigid Dome. Rev Cie Téc Agr [online]. 2018, vol.27, n.2, pp. 1-8. ISSN 2071-0054.

The work shows an analysis of Von Mises tensions of biodigesters of rigid dome (Chinese type), which are the most extended under Cuba conditions. For the above-mentioned, a professional software of design CAD was used. These investigations were executed based on Attended Design for Computers (CAD) as well as on the use of the physical simulation to small scale in plastic biodigesters and taking mensurations to real scale. The objective of the work was to compare the correspondence between the results obtained in the variable pressure of biogas obtained to laboratory scale and the values reported by other authors to pilot scale against the pattern on-line used. By means of the on-line pattern, the most dangerous sections in the different constructive elements that conform the biodigesters of this constructive type could be determined. It was possible to determine that the tensions that cause the interior pressure of biogas generated in these biodigesters of rigid dome (Chinese type), do not constitute dangerous tensions affecting the structures of walls, dome and neck of this biodigestor type

Keywords : von Mises tense; biodigesters; computer simulation.
