Abstract.

Two alternatives of the construction of the vibroacoustic isolator with the composite material layer are considered in the paper. The stress-strain state of the construction is obtained on the basis of the finite elements method. The moment scheme of the finite element for the weakly-compressible and composite materials is used in order to improve convergence of results. Influence of the volume content of composite fibers on the value of the vibration isolator settling was analyzed by means of the program complex «МІRЕLА+». Analysis of stress-strain state of the vibration insulator showes that increase in the proportion of fiber (from 0 to 0.3) reduces the maximum draft of construction for 25-30% regardless of the location of the composite layer.
