Способ относится к машиностроению, а именно, к испытаниям с целью определения усталостных характеристик деталей. Испытание нескольких образцов проводят на высоких уровнях нагрузок, результаты которого используются для построения наклонного участка кривой усталости, по ним и кривым усталости материала детали, полученным из справочника, определяются коэффициенты снижения предела выносливости. Путем деления значения предела выносливости материала на усредненное значение коэффициента снижения предела выносливости вычисляется предел выносливости детали. Кривая усталости строится с использованием результатов испытаний на высоких уровнях нагрузок и значения предела выносливости детали. Способ позволяет ускоренно на минимальном количестве образцов расчетно-экспериментальным путем строить кривую усталости детали.The method relates to mechanical engineering, namely, to testing to determine the fatigue characteristics of parts. Testing of several samples is carried out at high levels of loads, the results of which are used to construct an inclined section of the fatigue curve, and according to them and the fatigue curves of the material of the part obtained from the reference book, the factors reducing the fatigue limit are determined. By dividing the value of the material fatigue limit by the average value of the fatigue strength limit reduction factor, the fatigue limit of the part is calculated. The fatigue curve is plotted using the results of tests at high levels of loads and the value of the endurance limit of the part. The method allows you to quickly build up a part fatigue curve on a minimum number of samples by experimental calculation.
