The main conclusions on the results of the calculation of the design of the attraction

According to the results of strength calculation, stiffness assessment, and fatigue design of the “Chain carousel” attraction design in accordance with the requirements of GOST R 52170-2003, the following conclusions can be made in the APM Civil Engineering program:

The developed finite element model makes it possible to reliably describe the configuration of the attraction, geometric characteristics, loading conditions.

Analysis of the results of the strength analysis showed that for given loads, the results obtained do not exceed the maximum permissible values.

When analyzing the stability of the system, it is determined that the shape of the product is resistant to the actual loads.

Analysis of the calculation of fatigue showed that the maximum stresses in the structure do not exceed the calculated endurance limit.
