Article purpose is establishment of a quantitative character for influence of structural parameters of a rubber-cable belt on tensile testing results of a standard belt sample and influence of structural parameters on distribution of stresses in a butt-joint connection. Article methodology is in model construction, stress state determination for elastic material of deformed shape located between cables of a sample by methods of linear theory of elasticity and in obtaining parameters of a stress-strain state of an elastic shell of a standard sample for cable tear out testing in a closed form. Influence character of geometric parameters of a rubber-cable belt on tensile testing results of a standard belt sample is established and it allows considering parameters during determining maximum stresses in elastic shell of a belt butt-joint connections. Influence character of a stress-strain state of a standard sample on geometric parameters of a belt is established. The results make it possible to determine a distribution of shear stresses in elastic shell of a belt in butt-joint connections considering the structure of connections based on testing the standard samples. This increases the safety of usage of butt-joint connections of rubber-cable belts and increases their lifecycle.

The purpose of research is determination of a dependency of a stress state for composite elastomer-cable tractive element with a broken structure on a nonlinear dependency of shear modulus on deformations in the elastomeric shell. Research methodology is in analytical solution of a model of a composite tractive element with disturbed structure and a deformation-dependent shear modulus of an elastomeric shell. Results are in constructing an algorithm for determining a stress state of a composite tractive element with broken structure and a deformation-dependent shear modulus. Scientific novelty is in determining a character of de-pendency for a stress state of a composite tractive element on a nonlinear dependen-cy of shear modulus on deformations. Practical application of research is in a possi-bility to determine the dependency of a stress state of a composite elastomer-cable tractive element on a nonlinear shear modulus allows considering the effect of this phenomenon on the tractive element strength and ensures an increase of its operation-al safety.

A generalized canonical mathematical model of multidimensional controlled mining transportation complexes and other technical systems in form by A.M. Letov is considered. A principle of symmetry and an algebraic concept are in the basis of the developed analytical methods of design. A principle of symmetry is realized on a set of indexes of roots of a characteristic equation of the system and on a set of indexes of phase coordinates of the mathematical model. The problem of quality of dynamic processes in time is reduced to an algebraic problem of distribution of roots of a corresponding characteristic equation in a complex plane. An analogy in a procedure of transformation of a characteristic determinant into a polynomial and a structure of elementary symmetrical polynomials of roots is established. A new formulation of an analytical representation of change of phase coordinates in time in a form of ordered determinants with respect to indexes of roots and indexes of phase coordinates is obtained based on residue theorem. An illustration of the developed analytical method of design is performed on a special case of a well-known controlled technical system of the fourth order.
