| Abstract |
The influence of elastic compliance of the float housing on the vibration perturbing moment in gyros with cylindrical floating suspension in the case of symmetric fluid outflow was studied in [1, 2]. It was shown that, for a sufficiently thick float housing made of a material of small density and large Young modulus, the influence of elastic compliance can be neglected, and one can assume that the float housing is absolutely rigid. In the case of collet fixation of the gyro at the working position, to ensure the heat withdrawal to the end faces, the device housing is constructed as an elastic cylindrical shell with rigid attachment on the end faces. The influence of the device housing elasticity in the case of symmetric fluid outflow through the end faces was considered in [3], and the influence of the nonsymmetric fluid outflow through
the end faces for the case of a rigid device housing was studied in [4].
We consider the influence of the perturbing moment of the floating gyroscope with elastic device housing in the case of nonsymmetric fluid outflow through the ends on a vibrating base in the case of translational and angular vibrations of the base. We show that the elasticity of the device housing and the nonsymmetry of the fluid outflow significantly affect the hydrodynamic perturbing moment. |
