Abstract

Rotem Company has designed and manufactured bogie for Diesel Multiple Unit (DMU) according to the European standard UIC615-4, which si normally used for designing bogie frame. Because the countries located in Middle East do not have their own regulations for bogie design, most of running bogies in Middle East are designed by using European standard UIC615-4. UIC615-4 specifies the loads that bogie frame should withstand, indicates the way of material data to be used and the principles to be during verification by analysis and test. The bogie frame depends on the load conditions and magnitudes which are subjected to during service and characteristics of materials they are manufactured from. From the above reason, Rotem Company has performed Finite Element Analysis and load tests on the bogie frame according to UIC615-4. This research contains the results obtained by the analysis and the load tests. Also, this research verifies that the bogie frame has a static strength and fatigue strength. The analysis is carried out using I-DEAS 12 NX Series and specially designed test jigs and equipment are used for the load tests.
