The article describes the history of finite element method development and its application in calculating the strength of mining machines. The essence of the finite element method is revealed. This method is to split the design into basic elements, each of which is characterized by the values of displacements and stresses, lumped in the nodes of the element. The comparative analysis of finite element method and numerical methods of calculation on durability of machine parts was done. As an example, the results of the design calculation of vibrational crushing mill used for fine grinding of rocks were shown. The conducted calculations enable one to design the vibratory mills with larger diameters of grinding chambers and the increased operational resource.
