Abstract：The impact performance of a tilting-pad journal bearing in a turbo generator was studied by means of simulation and test.The shock stiffness of the bearing was considered as the only unknown quantity in a black box and it was identified through comparing the simulation result and the test result in various shock test cases.It shows that the shock characteristics of the tilting-pad journal bearing can be simplified as an equivalent non-intersecting stiffness parameter, and there is a simple formula relation between the shock stiffness and the shock velocity which is loaded to the bearing and represents the shock energy.
