Firstly, in order to measure the impact response characteristics accurately temperature compensation method for air film thickness of bearing is proposed and confirmed by experiment of bearing reaction force with air film thickness. Then, in this study, impact experiments were conducted with the optimized bearing and spiral grooved bearing and compared with theories of linear and non-linear analyses. As a result, the optimized bearing showed the high impact resistance compared with spiral grooved bearing. In addition, it was confirmed that the results of non-linear analyses are good agreement with those of experiment. Finally, based on above results, the impact response calculations of both bearings by non-liner theory under more high impact force condition were conducted. As a result, it is found that the response of spiral grooved bearing generates the self excited vibration.
