| Abstract: | Adiabatic thermal transient behavior of tilted pads thrust bearing under step load change was studied.The models of oil film and the parts of bearing were established,and it was solved by value methods.The responses of the bearing kinetic parameters were present.The influence to the thermal behavior of journal bearing by the initial steady pressure and rotational speed was discussed. |
