Stiffness Control

The article considered the assessment of the technical condition of a petal bearing with adjustable stiffness. A schematic diagram of bearing stiffness control is presented. Revealed a constructive solution providing rigidity adjustment. For a qualitative assessment of the technical condition, a petal bearing was modeled in the VATCAD environment. The schematic diagram and block diagram of the control system of the experimental stand for assessing the technical condition of the petal bearing are described. Recommendations are given for the further application of the concept of assessing the technical condition of petal bearings.
