【 摘 要 】

The problems of determining the probabilistic properties of the stress-strain state parameters of dynamically loaded systems with the application of modern software are considered. The advantages and possible risks of using the multifunctional ANSYS software in probabilistic analysis and reliability calculations of dynamically loaded systems are analyzed. Peculiarities of software application have been revealed taking into account the character of the changes in the probability density distribution of the stress-strain state parameters of dynamic system in the frequency intervals in the vicinity of the resonance zone. Qualitative and quantitative comparison of the results of probabilistic characteristics calculated in ANSYS software with analytical solutions has been carried out.
