Statistical Modeling for Assessment of Dipper Stick Service Life

Abstract: This paper presents an evaluation of the minimum dipper stick service life in the unsafe cross-section; it is based on statistical simulation known as Monte Carlo method. Source data on the bearing capacity parameters as well as on the values of stresses in the unsafe cross-section are presented as small samples. Statistical simulation is used to create a finite general population of data on machine parts my means of an intermediate subpopulation using order statistics distributions.

“…Shear processes of elastoplastic deformation include the sliding mechanism, which manifests itself in the movement of one part of the grain in relation to another. Outwardly, the manifestation of this movement is expressed by the formation of slip bands on the metal surface [21][22][23][24][25]. Analysis of the photographs shows that when evaluating the roughness, which determines the operational properties of the product, on the surface under study there is a large number of randomly located processing traces -protrusions and depressions.…”

“…Для расчета напряженно-деформированного состояния оболочечных конструкций при комплексном воздействии тепловых и механических нагрузок в настоящее время чаще используются численные модели [3,8]. Однако аналитическое моделирование [10][11][12][13] позволяет, прежде всего, выявить закономерности и объяснить нетривиальные особенности механизмов разрушения тонкостенных оболочечных конструкций, адекватных экспериментальным данным [9][10][11], на основе достаточно простых аналитических соотношений, получаемых из наиболее общих систем уравнений при использовании ряда допущений.…”

“…Имеющиеся в литературе [1][2][3][4][5][6] экспериментальные и теоретические оценки разрушения, вызываемого тепловым воздействием КПЭ, носят разрозненный и в основном качественный характер из-за отсутствия надежных данных как о количественных значениях параметров исследуемых процессов, так и о механизмах, вызывающих разрушение. Источники локализованного нагрева могут иметь различную физическую природу, в том числе могут быть вызваны воздействием мощного лазерного излучения [2][3][4][5][6][7][8][9].…”

“…The broad technological capabilities of vibrowave technological systems are the most effective means for obtaining high-quality, from the point of view of ensuring operational properties, coatings for various functional purposes on the surface [1][2][3][4][5][6][7][8][9][10][11][12]. Feature of the coating method considered in the article is that it is formed on the metal surface as a result of shock-pulse interaction of free-moving indenters in a closed volume under the influence of low-frequency oscillations.…”
