Ефективність віброударного нелінійного поглинача енергії (vibro-impactnonlinearenergysink - VINES), тобто вібро-ударного демпфера, значною мірою визначається його конструкцією. Оптимальний дизайн демпфера можна підібрати за допомогою процедур оптимізації. Однак результат їхньої роботи неоднозначний, їхні різні варіанти показують різні значення оптимальних параметрів демпфера. Ретельний аналіз отриманих значень параметрів дозволяє підібрати оптимальний варіант за певним критерієм. Проводячи цей аналіз, ми спостерігали багато цікавих явищ, а саме синергетичний ефект багатьох параметрів, багату комплексну динаміку VI NES, наявність прямих ударів між демпфером і головним тілом, залежність повної енергії від параметрів збуджуючої сили. Аналіз також дозволяє сформулювати обмеження VI NES. Всі ці проблеми відображені в цій статті
The efficiency of a vibro-impact nonlinear energy sink (VI NES), that is, a vibro-impact damper, is largely determined by its design. The optimal damper design can be found through optimization procedures. However, the result of their work is ambiguous, their various options show different values of the optimal damper parameters. A thorough analysis of the obtained parameters values allow you to select the best option according to a certain criterion. While carrying out this analysis, we observe many interesting phenomena, namely, the synergistic effect of multiple parameters, rich complex dynamics of the VI NES, the presence of direct impacts between the damper and the main body, the dependence of the total energy on the exciting force parameters.The analysis also allows us to formulate the limitations of the VI NES. All these problems are reflected in this article.
