Reshevska K. Strain-deformed state of elastomeric elements in the conditions of contact interaction

The research object - the deformation of elastomeric structural elements of contact interaction. The subject research - the parameters of the stress-strain state of elastomeric structural elements in a contact interaction. A Purpose of work - the definition of the stress-strain state of elastomeric structural elements of complex shape under conditions of contact interaction in three-dimensional formulation. Methods: in determining the stress-strain state of structural elements of elastomer used modification of the finite element method - Moment scheme of finite elements for weakly materials, the development of the iterative process of solving the problem of contact interaction of elastomeric elements with other elements of design are the use of variational methods. The basic ratio of the stiffness matrix of three-dimensional finite element using the Hermite interpolation polynomial based on the Cosserat finite element schemes for weakly materials. On the basis of the variational method developed by an iterative process of solving the contact problem for elastomeric structural elements using the finite element moment scheme for weakly compressible materials. Created software package for calculating the stress-strain state of elastomeric structural elements taking into account the contact interaction. The analysis of the stress-strain state of elastomeric vibration isolators VR-201 VR-203 VR-204, a cylindrical elastomeric mounts and lining. The proposed approach to the calculation of napruzheno-strain state of elastomeric structural elements in contact interaction has been introduced in the department of mechanics of elastomeric structures Geotechnical Mechanics Institute in the calculation of the stress-strain state of the rubber lining of vibration isolators. Branch of implementation -. engineer, agriculture, aerotechics and building industry.
