Analysis of dynamic effects acting on the turnout constructions

By Jan Hajniš

Abstract

Author´s name: Jan Hajniš School: Technical University - VUT, Brno Faculty of Civil Engineering Veveří 331/95, 602 00 Brno Program: Construction and Transportation Engineering Title: Analysis of dynamic effects acting on the turnout constructions Consultant: Prof. Ing. Jaroslav Smutný, Ph.D. Number of pages: about 70 + attachments Number of attachments: about 40 Year: 2012 This work describes the size and the process of dynamic effect – vibrations and shift – cockles in crossing panel and switch panels of the turnout constructions on steel and concrete sleepers in time and frequency domain. It compares the results of the measurement between these turnout constructions. Dynamic effects are undesirable physical phenomena for operation each train. It is therefore necessary to eliminate these phenomena as much as possible. The result of this test will by means of software programm and measuring set help to determine precisely the advantages and disadvantages of using both turnout constructions, or even to propose their improvements or dimensions
