Stability of energy-saving adaptive journal hydrostatic bearing with a restriction of the output lubricant stream

The paper discusses issues of quality of the dynamics for adaptive radial hydrostatic bearing with a restriction of the output lubricant stream. The article presents a mathematical model of support, an analytical dependence for the transfer function of the dynamic compliance for the linearized nonstationary model. It is established that reliance can operate stably at modes of negative compliance. This provided an acceptable quality indicators of dynamics for free and forced oscillations. Sustained bearing has a limited region of negative compliance. Design of bearing for ordinary throttling input lubricant is prone to fluctuations, but in this area has a sufficient margin of stability.
