The Static And Dynamical Research And Simulation Of Journal Bearings

Oil-lubricated journal bearing is an important class of bearing ,It have practical value to analyze it,it is selected as researching object in the thesis. The thesis bases on Reynolds-equation and researches the working state under the static and dynamic loading situation of the object. Under the static loading situation,the steady-state center position of journal is an important parameter,it is discussed,especially under three-lobe bearing,the calculating progress of it has a detailed description,and the progress is practiced by the means of computer programmer. Under the dynamic loading situation,the method of Hahn and Reynolds boundary condition are used to calculate the journal center trail of plain journal bearing. This progress is made into computer programmer too. The progress of calculating the journal center trail of three-lobe journal is another way different from plain journal bearing. In this way the method of Holland is used,and the progress is discussed too.In the thesis computer programmer is made in principle of convenience,flexibility and face to face. It use the technology of OOP,and make use of circumstance of VC++ 6.0 to make programmers have the effect of multimedia.
