Аннотация: The article considers the design, mathematical modelling and theoretical study of dynamics quality on aerostatic thrust bearing with external combined air double throttling and flow cavity. The use of the finite-difference method for solving boundary value problems for linearised and Laplace-transformed Reynolds equation allowed to obtain its solution with high accuracy. The quality indicators of bearing dynamics were studied depending on the damping and throttling resistances, as well as on the volume of the cavity. It is established that the presence of a cavity contributes to a significant improvement in the quality indicators of the bearing dynamics. Based on the analysis of the data obtained, conclusions are drawn confirming the hypothesis that with a targeted choice of the values of the external throttling system parameters, a design can be obtained that, in comparison with the known aerostatic bearings, will have much better dynamic characteristics. #320: 30
