The central and outer layers are assumed to be thin load-bearing, and the deformation in them is described by Kirchhoff’s hypotheses. The two relatively thick cores are lightweight, so that Timoshenko’s hypothesis is valid for them. A system of partial differential equations of motion is obtained using a variational method. An analytical solution to the problem is obtained by expanding the sought-for displacements into a series of orthonormal eigenfunctions. A numerical analysis of the resulting solution is performed.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"55 2","pages":"124 - 133"},"PeriodicalIF":0.4,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147617959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying dynamic programming theory to vibration protection systems as cyclically controlled objects, relationships are derived that, by linking the components of the system’s state vector and the control, enable the implementation of a local minimum principle procedure for finding the optimal positional control function for typical performance indicators that are clearly independent of control. For the vibration protection system under study with a controlled dynamic damper, optimal positional control of the intermittent damping process is found. It is established that this system possesses unique antiresonance and shock-resistant properties: resonant phenomena are eliminated, and transient processes are damped within a single period.</p>","PeriodicalId":642,"journal":{"name":"Journal of Machinery Manufacture and Reliability","volume":"55 2","pages":"170 - 178"},"PeriodicalIF":0.4,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147617955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concept of a digital twin is presented as a dynamic virtual copy of a physical object, integrating data from IoT sensors, deterministic models, and an analytics platform. Particular attention is paid to multicriteria optimization methods, including evolutionary algorithms (NSGA-II) and methods for finding compromise solutions based on Pareto optimality. Using the example of optimizing a chemical reactor, the practical implementation of an approach that made it possible to achieve a balance between product yield, energy consumption, and environmental performance is demonstrated.
