| Abstract: | Through the analysis of lubricating equation of externally pressurized gas journal bearing with orifice compensated,the two step partially differential equation was lowered to single step with optimization of variation functional.Adopting finite element method and using the triangle cell linear interpolation function to simplify the calculation of pressure distribution equation and optimize parameters of bearing,the pressure distribution,carrying capacity and stiffness of bearing were obtained.The influence of the factors such as bearing interval,partiality rate on carrying capacity and stiffness of bearing was analyzed. |
| Keywords: | externally pressurized gas journal bearing static characteristic finite element method orifice compensated |
