Abstract
This article presents a research approach that enables the assessment of the technical condition of complex technical objects. The main emphasis is placed on the load-carrying structures of these objects. The procedure applying experimental research techniques and computer computations using the finite element method is described. The combination of the two techniques assesses the technical condition of the structure. The described approach is presented using the example of two objects.
Highlights
In the case of the assessment of the technical condition of the load-carrying structures, the mostthe case of the assessment of technical the technical condition ofload-carrying the load-carrying structures, the case of the assessment of the condition of the structures, the mostused calculation approach is based on the finite element method
The findings revealed that in the case of the most unfavorable operating conditions, the structure will buckle
Dedifferences, the process of assessing the technical condition consisted of the same steps spite the differences, the process of assessing the technical condition consisted of the same of evaluation: preliminary visualvisual inspection aimed at detecting irregularities, examining steps of evaluation: preliminary inspection aimed at detecting irregularities, examthe technical condition quantifying the detected defects, and numerical calculations to ining the technical condition quantifying the detected defects, and numerical calculations establish their impact
Summary
The aim is to use existing facilities for as long and as safely as possible This requires periodic assessment of the technical condition based on which steps are taken to ensure the safety of their operation [19,20]. The assessment of technical condition is a complicated and time-consuming process; in the case of fatigued and old (often more than 20 years) load-carrying structures, it is difficult. Based on the assessment of the technical condition, a renovation policy is established, which extends the service life of the facilities Such activities may lead to modernization; an. Such a plant is characterized by difficult operating conditions (destructive weather, chemical environment accelerating corrosion, operating conditions (destructive weather, chemical environment accelerating corrosion, and additional heat loads) The purpose of this stage is to detect structural deficiencies and identify areas inspection.
