    Ecological solutions for freight trains by Martin Chýle, Michal Drábek

    Published 2023-11-01
    “…Attention is paid to the transport of freight trains on electrified lines with higher gradients (up to 25‰), alternatively with the possibility of a trip to non-electrified lines and sidings, which generate significant extra costs in the operation of trains and are often a reason for the carrier to deploy a locomotive of independent traction (diesel-electric) even in electrified line sections, even at the cost of increased operating costs and increased emissions. …”

    Dynamic Response of Railway Bridges under Heavy-Haul Freight Trains by Ye Xiao, Xiaoyong Luo, Jinhong Liu, Kun Wang

    Published 2020-01-01
    “…In this paper, a three-dimensional coupled finite element (FE) model of a heavy-haul freight train-track-bridge (HHFTTB) is established using multibody dynamics theory and FE method, and the DR for the coupled system of HHFTTB are solved by ABAQUS/Explicit dynamic analysis method. …”

    Adhesion control research for freight trains based on an improved sliding mode extremum seeking algorithm by CHENG Xiang, TANG Runzhong, HUANG Gang, HUANG Yishan

    Published 2023-01-01
    “…This paper presented an improved sliding mode extremum seeking control (SMESC) algorithm with time-varying parameters, as a solution to steady-state oscillation and slow convergence speed of the traditional SMESC algorithm in tracking the optimal adhesion point of freight trains. In order to weaken the steady-state oscillation and speed up the convergence speed of SMESC, the mathematical relationship between the gain parameter and steady-state amplitude in SMESC and the correlation between the slope of auxiliary function and convergence were analyzed and optimized. …”
