For train builders or in modernization projects, authorities require you to prove with calculations that there is no risk of fatigue damage in the vehicle. There are areas like all the welding joints and base material that need to be assessed. All these calculations can be done manually, but it is a very time consuming task, which can take weeks. And if you need to make changes to your vehicle, all these calculations need to be redone. Time is money is an old saying!
Another important area is the authority approval process. Today there are specific standards in this area, in Europe which need to be met, before authorities approve the vehicle for commercial use. So having a solution which would perform these tasks in just a few hours, could really help you speed up things and save a lot of time and money. To automate these tasks, the LIMIT software application suite was developed.
With LIMIT, stress assignments for different structures and materials are possible - according to various guidelines and engineering standards. Benefits of LIMIT:
Fast and efficient assessments of welding seams and base material
LIMIT has a very intuitive workflow, which makes the whole process smooth and easy. Read more about the workflow here.
Also LIMIT support interface to all well accepted tools like ABAQUS, MSC NASTRAN etc.
LIMIT offers three different types of strength assessments:
Variable amplitude fatigue strength
These assessment types can be used for base material and welded structures, depending on the design code. LIMIT enables different types of structural strength assessments according to numerous design codes and guidelines. Read more about the standards supported here.
