Rail Vehicles


The logistics passageways world map has already started to change due to the increased trade between the western countries and these of the emerging markets. This change will also shape the Freight segment of rail industry since transportation through high speed connections will play an important role in the logistics passageways change.

In addition, the passenger transport segment is also expected to expand. In most cases, cities are geographically restricted from expansion and with the growing of the populations are becoming denser. The movement of the masses in the bigger cities has constituted the investment in rails a beneficial investment. ANSA / META pre- and post- processing suite finds extensive application in the rail industry for setting up a model and reading results for analyses such as those for safety, comfort, prediction of loads on tracks, brake systems, or even accident reconstruction.

Solutions Highlights

ANSA shell and volume meshing covers even the most demanding quality requirements in considerable less time than the other commercial available software. Among others it offers state of the art capabilities for boundary layers element deployment, hexahedral dominant and pure hexa meshing, acoustic cavity mesher, wrapping, and one step mesh generation on automatically extracted middle surfaces. The augmented check toolbox of ANSA can easily evaluate the quality of the mesh based on the quality criteria and through the numerous manual or automated mesh handling functions the mesh can be easily optimized.

As the role of composite materials is growing, failure prediction studies are becoming increasingly important. Our suite offers a complete solution in composite materials modeling. These solutions are realized through numerous functionalities and features such as the mapping of laminates information, derived from CAD-based software, to discipline specific FE mesh model. This procedure leads to the lossless assignment of material orientation, material definition, element thickness per layer, and element orientation per layer. Within, META the user can modify material properties to re-evaluate the failure criteria.

NVH simulations are common in the industry, to determine for example the comfort level in terms of noise, and ANSA offers established solutions for the NVH discipline. Through ANSA cavity meshing and fluid structure coupling can be used within a single software environment, while modal models components can be effectively handled. META optimized performance for graphics memory usage and processing time along with a broad range of features and calculation options makes it an efficient environment for handling all NVH post-processing requirements.

On top of the unmatched meshing capabilities and the geometrical feature treatment, the connections modeling through representations and automatic definitions makes ANSA the most efficient solution for powertrain pre-processing.

Moreover, Through the Kinetics tool of ANSA our users have an advanced Multi-Body Dynamics (MBD) solution to perform motion analysis, to study and analyze the dynamics of mechanical systems such as suspensions.

META stands out from the competition due to its organization capabilities, the variety of tools for the assessment of the results, the available functionalities for the identification of the areas of interest and hot spots, the tools for direct calculations based on solver results, the options for the communication of the results, and for its automation capabilities.
