Kinetic Impulses - Impacts On Rotating Rigid Rotor Bearings

 

Katica Stevanović - Hedrih

 

This paper is dedicated to the memory of Academician Valentin V. Rumyantsev (1921-2007) and contains a short review of his results in the area of stability of permanent rotations of a heavy rigid body, and the stability of rotation of a heavy rigid body with one fixed axis as well as the stability of gyroscopes.    

Using the vector of the rotor’s mass inertia moment, with respect to the rotation axis through the spherical bearing and the corresponding vector of the rotation rigid rotor mass deviational moment, the kinetic impulses- impacts to the rotor bearings are expressed. It is clearly visible that these two components are of opposite directions and that they constitute a deviational couple of kinetic impulses. The paper gives the graphical presentations of the rotator vector intensity as well as its angular velocity in a function of the angular coordinate

Key words: vectorial analysis, vector calculus, impact loading, kinetic impulse, moment of inertia, rotor.
