Noise generated by railway wagons in operation is produced large numbers of noise sources. Although the transport considered to be environmental friendly, especially production CO2 emissions, one problems that should solved keep competitive and sustainable future. In EU, there a strong permanent legislation pressure on interior exterior reduction transport. last years Slovakia, besides moderniz...

The publication updates the issue of wagon repair in modern conditions and highlights main problems associated with method organization work. Low productivity is due to outdated equipment worn-out rolling stock, poor training staff involved. article contains provisions changing repair, calculating possibility loading production positions, program repairing wagons, determining number ways their ...

In a sampled data system, frequency components greater than half the sampling rate "alias" (shift) into the frequency band of interest. Most of the time, aliasing in an undesirable side effect, so the "undersampled" higher frequencies are simply filtered out before the A/D stage. But sometimes, the undersampling is deliberate and the aliasing causes the A/D system to function as a mixer. This a...

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...

Urban transport problems in Pakistan are managed by building larger and better roads. By contrast, the principles of sustainable transport encourage using lowcost public transport that could perform well in mixed land use and high density Pakistani cities. The purpose of this paper is to provide a critical overview of public transport policy in Pakistan from the British India period through to ...

regarding increasing importance of tank wagons and efficiency in fluids transportation, their usage is increasing every day. thus paying attention to their designs just as dynamic analysis of wagons during travelling time is vitally important. in this task, sloshing coefficient as prominent parameter in tank wagons designing has been investigated. to ease of efficient design, theses parameters ...
