Reducing the vibration activity of low-noise fans is becoming the most important direction in the creation of their new modifications. It is analytically shown that the efficiency of vibration damping of a mechanical system depends not only on the ratio of natural frequencies, vibration frequencies and damping coefficient, but also on technical solutions for installing dampers, for example, on an elastic or rigid foundation. The article proposes an algorithm for minimizing the vibration activity of a mechanical system which is an axial low-noise fan. To solve the problem of minimizing noise in the operating mode of the fan, an innovative technical solution for the construction of the case is being considered - the walls are made in the form of a “sandwich” consisting of layers of structural materials that provide strength characteristics, as well as noise and vibration protection.
