Justification of the method of calculating the cylindrical mesh shell
Incoming article date: 01.11.2021Studies of a cylindrical mesh shell using the method of decomposition into flat faces and the LIRA application software package have been carried out. The assessment of the possibility of using the considered approaches in the analysis of specific sites and in the case of a complete study of the mesh surface is carried out. The necessary indicators of inclusion in the work of the design, reliability, accuracy and speed of calculation of design parameters are determined. The characteristics of the stress-strain state of the system are revealed, which made it possible to recommend an approximate calculation method for quickly determining preliminary results. Methods of obtaining calculated data in all zones of the shell on a cylindrical surface are analyzed. With the help of application software, a high degree of information about the forces, displacements and mass of the spatial structure was obtained. The simplicity and clarity of visualization of the obtained schemes in accordance with the design requirements are noted.
