Parallel computing and co-simulation in railway research
International Journal of Rail Transportation Special Issue Call for Papers
Deadline: 15 April 2019
Due to the high cost of physical testing and the increasing acceptance of computer simulation modelling, railway research has become more and more reliant on computer simulations to advance the state-of-the-art. With the collective efforts of researchers from all around the world, computer models and simulation techniques in railway research have been developed to advanced levels incorporating unprecedented amounts of detail. For example, three-dimensional wheel-rail contact models, traction models with consideration of gear transmission and mechatronic control, discrete element ballast models and multi-body draft gear models are now available. However, these advanced models are often developed from the perspective of different research interests and by various researchers using different programming tools. In real-world railway engineering, computing models that require multiple detailed model components are sometimes needed. There are also motivations from a theoretical research perspective to integrate multiple detailed model components as such a combination does provide more accurate simulation results. In these cases, there is a research question about how to connect legacy models that were developed by different researchers and often using different programming tools so as to avoid developing new models from scratch. The reason is obvious as new developments are time consuming. Under these circumstances, co-simulation is an effective approach to resolve the question. Co-simulations can be achieved in various ways, such as shared memory and communication protocols. Also, the co-simulations can be achieved among different software packages no matter whether the packages are in-house or commercial.
Simulation models in modern railway research tend to become more and more complex. This can be about developing a model with more details or extending a model to include more components like the co-simulation issue discussed previously. More complex models often inevitably increase the computing time for simulations. And sometimes the bottleneck is not about not being able to develop detailed models, but the impractically long simulation time that is required to compute the simulations. Also, modern railway research needs to solve some naturally large scale computing problems, such as optimisation of train scheduling, Finite Element Analysis of vehicle body structures and the aerodynamics of high speed trains. For these research topics, the computing speed issue has always been one of the major challenges. Therefore, besides developing more detailed models, another main factor that is needed to advance railway research is to increase computing efficiency.
The above discussions can lead to a conclusion that parallel computing and co-simulation are important approaches to further advance railway research. Both techniques have been used and reported upon in railway publications. However, there is still significant room to leverage their applications.
Given this situation, a special issue on “Parallel computing and co-simulation in railway research” is proposed to be published by the International Journal of Rail Transportation.
The objectives include:
- Promote the applications of parallel computing and co-simulation in railway research
- Identify more application topics for parallel computing and co-simulation
- provide a communication media for researchers who are already using parallel computing and co-simulation.
Special issue scope
