History

The Project CONVURT (CONtrol of Vibrations from Underground Rail Traffic) is established as a grant funded project under the 5th Framework of the EU Programme for Research, Technological Development and Demonstration. It was approved within the Growth 2000 call for tenders. The project combines the resources of ten Partners comprising metro operators, research organisations, universities and industry. CONVURT commenced on January 1st 2000 and its duration is three years.

Project Overview

Electrified underground rail systems provide the apparent solution to mass transport of people in cities but their future success and growth require a high degree of eco-efficiency. Metro rail systems cause vibrations which create noise disturbance in adjacent habitation. CONVURT is aimed at creating the innovative tools where ground borne vibrations can be predicted and minimised. The proposal is to create a validated computer based prediction model as well as prototype innovative vibration reducing products, both able to be applied to worldwide sales. CONVURT will also develop novel monitoring and maintenance techniques that will prevent deterioration of vibration performance with time. The project will make unique, invaluable input to the development of ISO rail noise standards and produce 'Best Practice Guidelines'.

Project Objectives

  1. To create validated innovative and quantitative modelling tools to enable prediction of locations where ground-borne vibration transmission and thereby noise will occur in metropolitan railway networks.
  2. To develop and evaluate innovative and cost effective track and tunnel equipment to reduce ground-borne vibration capable of being retrofitted and exported worldwide.
  3. To provide scientific input to allow the preparation of International Standards.
  4. To prepare Good Practice Guides for underground railway operation in order to maintain minimum vibrations for the lifetime of operation.
