Abstract.

For the decision of task of dynamic deformation of elastomeric elements a mathematical model is developed and the method of calculation of constructions is offered taking into account physical and geometrical non-linearity of nearly incompressibility of viscoelastic bodies. Nearly incompressibility of elastomers shows up during the straitened deformation of rubber elements and deformation of skims of rubber elements in rubber-metall constructions. For description of nonlinear viscoelastic properties of elastomer the of Peng-Landel’s law, Lindli’s law, modified Hooke’s law are used. As a kernel of relaxation the kernel of Rabotnova is used. Amplitude of vibrations of shock absorber is determined from the finite element method decision of task of dynamics with the use of N’yumark’s scheme.The offered method is used for the decision of the linked problem of thermoelasticity and calculation of longevity on the basis of power criterion.

Keywords:
