Abstract in different language: Van der Pol introduced a solution of the self-oscillations of spring suspended body siting upon the uniform velocity moving rough conveyor belt in 1934. Friction between body and conveyor belt was non-Coulomb, which characteristics has negative slope in the certain interval - see Fig. 1. This classic problem, which is introduced in lots of non-linear vibrations related textbooks, motivated several works whose refer to the fact that solution leads to the same equation (such as pin rotating in hub). Chernikov in demonstrates that transformation of one-axis gyrostabilizer self-oscillations lead to the same equation in certain case. Mentioned Chernikov�s work motivated us to analyze selfoscillations of two-axis gyroscopic stabilizer with non-Coulomb friction in the axis of stabilizer outer gimbal caused by uniform rotation speed of the stabilizer base.
