Possibility of multiaxial test simplification of rail vehicle bogie frames

Abstract

The multi-axial loading is usualy used for experimental fatigue tests of rail vehicle bogie frames. These tests are expensive, time-consuming and depended on laboratory equipment afterwards.For this reason it is preferable to test only the most exposed parts of construction. The aim of work was to determine possibility to find a solution for reduction of total number of actuators. In the paper was described specimen design process and its optimalization. In the next part was discussed procedure of transformation of triple-cylinder multi-axial test to double-cylinder test or single-cylinder test. Theoretical results will be verified by experimental tests.
