Abstract The article considers the force interaction contact problem of a guide roller with a mine conductor during the movement of a mine lifting conveyance on the example of a model problem of the contact interaction of a torus with a beam. The model problem analytical solution is considered, a finite element model of the system under study is developed. Contacting bodies materials elastoplastic behavior was taken into account when solving the problem. The various contact types between guiding roller and the conductors were considered. The values of critical loads leading to plastic deformations occurrence in a conductor with various types of contacts are determined and their relationship with the friction coefficient value is established. Comparative analysis of the obtained analytical and numerical results demonstrates a high degree of correlation.
Keywords guide roller, mine conductor, contact interaction, finite element analysis, friction contact, elastoplastic material
