Car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. Though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. To do so, car body acceleration is determined using a 10 DOF simulat...

The purpose of this scientific work is to optimize operating activities in the Republic Uzbekistan with a two-parameter (wagon and cargo сommercial) component, which has direct access rail transport infrastructure. Methods are used system analysis graphic modeling. activity railway operators analyzed. Described an exemplary existing location scheme enterprises operators, infrastructure Uzbekist...

A framework is described for predicting the airborne noise inside railway vehicles which applied to rolling sources. Statistical energy analysis (SEA) used predict interior by subdividing train cabin into several subsystems. The dissipation loss factors are obtained from measured reverberation time in cabin. power input SEA model external sources multiplying incident sound on surfaces with tran...

In South Africa, one of the main lines situated in its Limpopo Province presents symptoms excessive vehicle-track vibrations. A modal method is adopted to study difference dynamic response corrugated rails resting on Hytrel/6385 and High Density Polyethylene (HDPE) rail pads. The results for these two types pads are analysed form Frequency Response Functions (FRFs). Two positions considered obt...

The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...
