Description Calculation models have been developed for railway induced ground vibration. In particular it has been established that it is important to include the two rails separately at higher frequencies but that they can be considered together at low frequencies. The effect of the train movement has also been determined.
The nonlinear behaviour of rail fasteners has been quantified through laboratory tests. The effect of this nonlinear behaviour on the vibration of the track and ground has been assessed using theoretical models.
Simple models for piled foundations have been developed and compared with more complex models.
The models have been implemented in fast-running software for predicting ground vibration due to railways. This includes surface railways and tunnels, including twin-tunnels.
Exploitation Route The software will be made available to the industry although not as freeware. To provide on-going support it has been decided that it is more appropriate to charge a modest licence fee. The stakeholder group will be allowed preferential access to recognise their contribution to the project.

PI Contribution We are using the ElastoDynamics Toolbox (EDT), which was developed at KU Leuven by Prof Geert Degrande's research group, to calculate Green's functions of homogeneous half-space and multi-layered ground. The project is a good opportunity to promote the work of KU Leuven by continuously acknowledging the EDT in published work and presentations. It also provides an opportunity to scrutinise the robustness of the EDT and its practical applications.
Collaborator Contribution Prof. Degrande has kindly supplied free of charge a version of the ElastoDynamics Toolbox (EDT) for the duration of the project. The EDT calculates Green's functions for a multi-layered ground. The EDT is based on the direct stiffness method and the thin layer method in order to model wave propagation in layered media. Prof Degrande was a member of the Stakeholders Group and attended its meetings. He was very supportive of the project.
Impact Several of the papers acknowledge the use of EDT

PI Contribution In the project we were in charge of WP1 and WP3. WP1 deals with developing novel excitation models accounting for non-linearity of elements of conventional track systems. The models utilise the dynamic stiffness and finite element methods considering both discretely and continuously supported tracks. WP3 aims to produce fast running software derived from the detailed models of generation and propagation of ground-borne vibration developed in WP1 and WP2. The new software, called MOTIV, will calculate efficiently train-induced vibration taking into account interaction between neighbouring structures, such as tunnels and buildings, and variation of soil stiffness with depth.
Collaborator Contribution Cambridge were a partner in MOTIV in charge of WP2 which aimed at developing detailed boundary element models for the dynamic tunnel-soil-pile interaction due to underground railway vibration. The developed models serve as a benchmark for models that are developed in other work packages at ISVR. Cambridge are also responsible for managing the project in terms of organising meetings, collaborating with industry partners, showcasing project outcomes and managing the project website (www.motivproject.co.uk).
Impact Most papers produced during the project have been authored jointly.

Primary Audience Public/other audiences
Results and Impact As part of the University of Southampton Science & Engineering Festival, an exhibit was created consisting of a Lego trainset. This was instrumented with vibration sensors allowing the public to listen to the vibration signals and to see them displayed on the screen of the computer. An additional activity was provided allowing children to identify different sounds. Posters displayed information about the research projects. A total of 6000 visitors attended the Festival with several hundred visiting our exhibit.

Results and Impact The visits to Pandrol UK (Worksop) and Centro (Birmingham) were conducted in order for our research team to inspect the facilities of these companies in relation to railway research. We also intended to discuss possible means of collaboration through measurement of rail roughness, track and ground vibration (Centro) and through laboratory testing on railpads (Pandrol). At the end of these visits, all the parties were fully committed to working together, as part of the MOTIV project, with the main objective of improving our understanding of railway induced ground vibration.

All parties involved agreed to collaborate with each other. The universities of Southampton and Cambridge will develop the numerical prediction models whilst Centro and Pandrol will support us in validating these models through the use of their facilities.
