Abstract.
We present the technique of calculating stiffness and dissipative parameters of massive cylindrical elements under deformations of monophasic contraction. The algorithm for solving the problem is reduced to: choosing the hardness coefficients; solving related problems of nonlinear thermoviscoelasticity and calculation of stress-strain state; building approximate relations to calculate the stiffness characteristics of the elements through the use of established laws; estimating their accuracy. Experimental studies were subjected to rubber and rubber-metallic solid and hollow cylindrical elements. Such elements have specific anisotropic properties: shear stiffness and may vary significantly from the compression one. The use of such effects is suitable for vibration of heavy machinery, as well as to protect buildings and structures from vibrations of technological and industrial type.
Keywords:
stress-strain state, massive rubber elements, stiffness and dissipative parameters, stiffness coefficients
