A unified formula for determining the values of coefficients of power polynomials makes it possible to rationally define the laws of motion without finite and infinite spikes in the synthesis of elastic cam-lever systems. This provides a rational determination of the laws of motion without finite and infinite spikes in the synthesis of elastic cam-lever systems, and simple verification of the accuracy of the results obtained. The functions are particularly suitable for the synthesis of polydyne cams, as well as cams, since one polynomial can be used throughout the entire geometric mechanism cycle.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Введение</title><p>Введение. Генерация полиномиальных степенных законов движения для синтеза кулачковых механизмов усложняется необходимостью определения коэффициентов степенных полиномов. Цель исследования  раскрыть рациональную возможность генерации степенных законов с произвольным числом членов при синтезе кулачковых механизмов. Материалы и методы. Методом так называемой трансфинитной математической индукции получена унифицированная формула для определения значений коэффициентов степенных полиномов с любым числом целых и/или нецелых показателей.   </p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. В этой исследовательской работе представлена унифицированная формула для определения значений коэффициентов, которая дает правильные результаты для любого числа четных и/или нечетных показателей. Многочисленные проверки, проведенные при разных числах четных и нечетных значений показателей степени пять и шесть степенных функций, подтвердили правильность вывода формулы. </p></sec><sec><title>Обсуждение и заключения</title><p> Обсуждение и заключения. Представлена унифицированная формула для определения значений коэффициентов, которая дает правильные результаты для любого числа четных и/или нечетных показателей. Это дает рациональную возможность определения законов движения без конечных и бесконечных пиков при синтезе упругих кулачковых систем и простую проверку точности полученных результатов. Эти функции особенно подходящее для синтеза полидинамичных кулачков, а также кулачков, поскольку один многочлен может использоваться на протяжении всего геометрического цикла  механизма. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кулачковые механизмы</kwd><kwd>законы движения</kwd><kwd>степенные функции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cam mechanisms</kwd><kwd>laws of motion</kwd><kwd>power functions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Levitsky NI.
