It is shown that is an actual mathematical  modeling of dynamic state blocks of radio electronic facilities (REFS), represent a heterogeneous structure, and in the early stages of design for informed decision design  u2012 technological solutions for creating vibration- and udaroustojchivyh designs. The method of application of autonomous units for the investigation of dynamic processes in heterogeneous structures with percussive effects. Created a mathematical model of dynamic process of study and numerical simulation of dynamic State implemented the electronic unit, a shock acceleration spectral density analysis and spectrum of natural frequencies for different materials fill. As a result, it has been proven that if you increase the rigidity of the material quantity electronic unit wash of natural frequencies of longitudinal vibrations in a given frequency range external perturbations decreases.
