Whereas, the deterministic design approach consists in achieving designs without considering the randomness of the design parameters that may lead to non reliable designs. In this work, we establish a statistical study on the randomness of the soil properties in collaboration with Cranfield University. This new study can be considered as a useful database for agricultural equipment design fields. Here, we take into account the uncertainties of soil mechanical properties that have big effects on tillage forces. The tillage forces are calculated in accordance with analytical model of McKyes and Ali with some modifications to include the effect of both soil-metal adhesion and tool speed. The distributions of soil-tool forces are next established to design soil tillage equipments such as shank chisel plow. The reliability index is then calculated using two deferent methods (Monte Carlo method and Hasofer and Lind approach). The Hasofer and Lind approach provides the structural reliability level with a low computing time relative to the Monte Carlo approach</p></abstract><trans-abstract xml:lang="ru"><p>Основной интерес конструкторов состоит не только в определении амплитуды сил, возникающих при обработке почвы, но и в их распределении при различных механических свойствах почвы с целью достижения надёжности конструкции. В связи с этим, детерминированный подход к проектированию состоит в разработке конструкции без учёта случайности выбора её параметров, которые могут привести к потере надёжности. В этой работе мы проводили статистические исследования рандомизацией свойств почвы в сотрудничестве с университетом Кренфилда. Данное исследование можно рассматривать как полезную базу данных для проектирования сельскохозяйственных орудий. Здесь мы принимали во внимание неопределённость механических свойств почвы, которая оказывала существенное влияние на её обработку. Расчёты сил сопротивления почвы проводились с использованием математической модели МакКейса и Али с некоторыми изменениями для того, чтобы учесть силы адгезии почвы с металлом орудий и скорость движения культиватора. Исследования сил сопротивления почвы послужили основой для проектирования почвообрабатывающего оборудования типа дизельного культиватора. Затем, с помощью двух методов (метода Монте-Карло и подхода Хазофера-Линда) был вычислен показатель надёжности. В результате подход Хазофера-Линда показал более высокую надёжность при меньших временных затратах на расчёты, чем метод Монте-Карло.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вероятностный дизайн</kwd><kwd>надежность конструкции</kwd><kwd>показатель надежности</kwd><kwd>почвообрабатывающие силы</kwd><kwd>probabilistic design</kwd><kwd>reliable design</kwd><kwd>reliability index</kwd><kwd>soil-tillage forces</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">Desbiolles, J.M.A. A Novel Approach to the Prediction of Tillage Tool Draught Using a Standard Tine / J.M.A. Desbiolles, R.J.
