Actions on a railway track, due to an isolated defect
(2014)The rail running table imposes to the vehicle a forced vibration. It is not smooth but instead it comprises a lot of faults that give to the rail running table a random surface. Furthermore under the primary suspension ... -
Actions on railway track panel and ballast-behavior of the Hellenic limestone ballast
(2009)In this paper a new method is presented for the estimation of actions on sleepers and the pressures that develop under the seating surface of the sleeper and are transmitted on the ballast. Results from the tests performed ... -
Ballast stressing on a railway track and the behaviour of limestone ballast
(2008)In this paper the results of the tests performed on the ballast used in the Greek network are presented. The tests were conducted in laboratories in France and Greece, and led to a change in the Greek technical specifications. ... -
Influence of a bent or battered joint or welding on the dynamic loads due to the non-suspended masses of railway vehicles
(2014)Train circulation is a random dynamic phenomenon and, according to the different frequencies of the loads it imposes, there exists the corresponding response of track superstructure. Random dynamic phenomena are generally ... -
Influence of rail pad stiffness on track stressing, life-cycle and noise emission
(2010)In this paper the results for the influence of the rail pad stiffness on the Railway Track stressing and its Life-Cycle is presented, as derived from a research program performed in Greece due to the appearance of extended ... -
Secondary Stiffness of Fastening Clips: Influence on the Behavior of the Railway Track Panel
(2016)Fastenings are all the materials whose function it is to structurally connect the rail to the sleeper. The fastenings used in concrete sleepers must be elastic in both tension and compression. The basic component of all ...
