Experimental investigation into the failure behaviour of insulated rail joints
Boyd, Paul, Mandal, Nirmal, Bandula, Thaminda, Zong, Nannan, & Dhanasekar, Manicka (2012) Experimental investigation into the failure behaviour of insulated rail joints. In Proceedings of the Conference on Railway Engineering 2012, Railway Technical Society of Australasia, Brisbane, pp. 53-60.
Ratchetting failure of railhead material adjacent to endpost which is placed in the air gap between the two rail ends at insulated rail joints causes significant economic problems to the railway operators who rely on the proper functioning of these joints for train control using the signalling track circuitry. The ratchetting failure is a localised problem and is very difficult to predict even when complex analytical methods are employed. This paper presents a novel experimental technique that enables measurement of the progressive ratchetting. A special purpose test rig was developed for this purpose and commissioned by the Centre for Railway Engineering at Central Queensland University. The rig also provides the capability of testing of the wheel/rail rolling contract conditions. The results provide confidence that accurate measurement of the localised failure of railhead material can be achieved using the test rig.
