STABILIZATION OF THE STRESSED STATE OF CRANE EQUIPMENT ARTICLES BY VIBROMECHANICAL TREATMENT

Crane equipment, being the main means of lifting various loads, is one of the responsible products, ensuring the working capacity of which is an important task. The main reason for their failure is destruction, due to the presence of residual stresses formed at the welding stage. To reduce their value, various methods are used, involving vibromechanical stabilizing treatment, which has a number of advantages. The study objective is to adapt the technology of vibromechanical stabilizing treatment of crane equipment in order to ensure its operability. This task is solved by using modern software tools that allow modeling the condition of crane equipment under various conditions. The paper uses finite element modeling as the main research method. The construction of virtual solid-state three-dimensional models of the article, the determination of its natural oscillation frequencies and the assessment of the stress-strain state were carried out by finite element method in SolidWorks. The study object was the article called "Balka". As a result of the conducted research, the main provisions of the methodological approach to the selection and improvement of the engineering scheme, modes of vibromechanical treatment, which ensures stabilization of the stress state of crane equipment articles without conducting a large number of experimental studies, are formulated.
