Aiming at the problem of low stiffness of aerostatic bearing. according to the principle of gas-solid coupling. this paper designs a kind of aerostatic thrust bearing with elastic equalizing pressure groove (EEPG) and investigates the effect of elastic equalizing pressure groove (EEPG) on the stiffness of aerostatic bearing. According to the physical model of the bearing. https://www.hindigyanvishv.com/
