== Abstract ==

​

Rail vehicles are directed along different routes through track switch systems. These switches are subjected to<br> high loads and vibrations which may introduce misalignment in the switch layout. The objective of the current<br> project is to develop a simulation model of a ‘self-adjusting’ switch. The switch should be able to detect the<br> existence of any misalignment (within a predefined range) between the stock rails and switch rails and will be<br> able to re-align itself. The first phase of the project is to model a working track switch system, High Performance<br> Switch System (HPSS), which is in operation in the UK. The multi-body simulation software Simpack is used to<br> model the switch panel and Simulink is used for modelling the actuator mechanism of HPSS. A co-simulation<br> environment is created in Simulink to construct the complete model of the switch system. The model has been<br> validated with the data available from the working switches. The second phase of the project will be to create<br> misalignment in the switch layout and develop a control strategy which will be able to adjust the misalignment.
