English abstract

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 dependency 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 possibility 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 operational safety.
