Abstract: Experimental results are presented to determine the hydraulic characteristics of highly metal rubber in the porosity range from 70% to 85% for wire samples with a diameter of 0.1–0.8 mm. It is shown that with an increase in the diameter of the wire with a fixed porosity, the pressure loss of the working medium on the metal rubber decreases. The generalized empirical expressions found for determining the viscous and inertial resistance coefficients depending on the porosity and diameter of the wire from which the metallorisn is made are presented.

Keywords: porous metal materials, hydraulic, viscous coefficient of resistance, inertial coefficient of resistance, metal rubber.
