英文摘要：

According to the existence of dimension errors on hydrodynamic journal bearing system, the experimental platform of hydrodynamic journal bearing system was established, the nonlinear dynamics analysis system based on software development platform of LabVIEW graphical programming language was developed, also the corresponding signal processing and module design works was introduced. The effects of the friction power loss brought by the dimension＇al errors of the bearing width, bearing diameter and journal diameter were analyzed, and the corresponding energy loss ＂experiment was conducted. The results show that different dimensional errors will hare varying degrees of impact on the system, and verified the consistency of the experimental and theoretical results of the dimensional errors on the energy loss of the rotor-bearing system. A theoretical basis to design parameters, tolerance and reduce energy consumption ofrotar system was provided.
