**Wave your WANDS and make wishes come true
--- Using 2.5D FE-BE model to investigate Railway induced vibration**
Railway induced noise and vibration have great impacts on environment and human life. They have been identified as major challenges for the European railway system during a time when the railway sector is constantly increasing its transport volume. Reducing the noise and vibration levels with sustainable measures is one of the major tasks for railway researches. Considering the cost and difficulty of carrying out field test, numerical simulations are widely used. Many models have been developed for predicting railway noise and vibration. As analytical models and 2D numerical models have always been doubted for being way too simplified, 3D models are normally way too time-consuming. A 2.5D FE-BE model, WANDS, was developed in ISVR during the past several years. By assuming structures are parallel on one direction (which is the case in most of railway systems, pipelines, underwater channels, .etc), it has the advantage of predicting 3D noise and vibration using much less calculation time than other 3D models. WANDS has been used to investigate railway induced vibration and abatement solutions for RIVAS project during the past two years, and its ability of investigating railway structures and ground vibration has been confirmed. Integration with other Railway models and further developments are expected in a near future.
