The structure and principles of a large -scale oil -film bearing comprehensive test rig are introduced.The calculation model for load characteristic is built through the stress analysis on the main shaft and considering the friction coefficient between the main shaft and bushing under different lubricating conditions,and the loading characteristic is obtained.The test rig run stably under low,medium and high speed and heavy load through the selection of an appro-priate DC motor,and the different operating conditions are simulated and the different tests are carried out.
