Furthermore, the effect of wind, which is not constant over time, can lead to vibration excitation in the linkage. However, the catenary must not leave a defined range of movement during operation in order to ensure reliable operation of the OH trucks with as uninterrupted a supply of electrical energy as possible and, in addition, to maintain minimum electrical distances between conductors and between conductors and adjacent elements as specified in the standards.<\/p>\n<p>The aim of these investigations is to record and analyze the position and vibration behavior of the chain drive under various boundary conditions in real operation and thus to demonstrate compliance with the defined limit values. For this purpose, a measuring system developed and tested by the TU Dresden is used to optically record the movement of the contact wires and suspension cables during operation with simultaneous local wind measurement.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3e4c3e8 e-con-full e-flex e-con e-child\" data-id=\"3e4c3e8\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6bd942a elementor-widget elementor-widget-image\" data-id=\"6bd942a\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*!

In order to be able to represent the operation of an eHighway system in a detailed and practical manner, the subsystems vehicle, route, electrical infrastructure and (driving) operation as well as their dynamic interactions shown in Figure 2 are simulated in the model. The simulation principle is based on a driving operation and drive simulation with combined electrical network calculation. The validation of the model is carried out against real measurement data recorded by the vehicles in field tests and has already shown very<\/p>\n<p>good agreements between simulation results and real measurements.<\/p>\n<p>The simulation model can be extended to any route and can be used as a technical decision-making basis for a route expansion or &#8220;roll-out&#8221; of the eHighway. With the help of the model, forecasts of electrical and operational parameters (energy and power demand, current load, voltage drops, etc.) are made possible for any operating scenarios. Furthermore, studies on system design and technical feasibility as well as considerations on ranges of on-board energy storage systems can be carried out.<\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-4acac556 e-con-full e-flex e-con e-child\" data-id=\"4acac556\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-547afc6 elementor-widget__width-initial elementor-widget-tablet__width-inherit elementor-widget elementor-widget-image\" data-id=\"547afc6\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"Modellierte Subsysteme des eHighway im Simulationsmodell (Quelle: Markus Werner, TU Dresden)\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6NTg0MSwidXJsIjoiaHR0cHM6XC9cL2VoaWdod2F5LXNoLmRlXC93cC1jb250ZW50XC91cGxvYWRzXC8yMDIzXC8wN1wvU3RlcGhhbl9TaW11bGF0aW9uc2F1ZmJhdV9kZS5wbmcifQ%3D%3D\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1264\" height=\"429\" src=\"https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de.png\" class=\"attachment-1536x1536 size-1536x1536 wp-image-5841\" alt=\"\" srcset=\"https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de.png 1264w, https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de-300x102.png 300w, https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de-1024x348.png 1024w, https:\/\/ehighway-sh.de\/wp-content\/uploads\/2023\/07\/Stephan_Simulationsaufbau_de-768x261.png 768w\" sizes=\"(max-width: 1264px) 100vw, 1264px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Modellierte Subsysteme des eHighway im Simulationsmodell (Quelle: Markus Werner, TU Dresden)<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-153d54c e-flex e-con-boxed e-con e-parent\" data-id=\"153d54c\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-363e1d7 e-con-full e-flex e-con e-child\" data-id=\"363e1d7\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-0070574 e-con-full e-flex e-con e-child\" data-id=\"0070574\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-84474ff elementor-widget elementor-widget-heading\" data-id=\"84474ff\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Prof. Dr.-Ing.
