eng	Method of Load Simplification of Multiaxial Fatigue Tests	In the course of fatigue tests of constructions of railway vehicles or infrastructure the lifetime is assessed by the stress in the weakest place of the construction (Critical place – CP). In some cases, only the fatigue testing of the part of the construction with the CP is possible. In this case an original load set is not applicable and a new load set must be proposed. A load in the CP equivalent to the load in the original construction will be achieved by a new load set. The method which will be described in the paper assesses (processes) the value of main stress σ1 and direction α as a function of time.	load simplification; multiaxial tests; fatigue; railway vecle; bogie frame;
