Abstract
- Rail wear is easy to measure, but the calculation of the permissible wear (al loss of cross section) is a challenge. Only in a few mechanical engineering fields is a strength analysis in a corrosive environment with simultaneously loss of cross section necessary. Part 1 shows an approach of the probabilistic calculation of the acting loads with a modern lifetime calculation is presented, which allows a more differentiated dimensioning of the permissible rail wear with knowledge of local load distribution processes. This requires a good database, which Switzerland now can use after a longtime of preparation. An overview is given of the distribution of guiding forces, modules of subsoil as well as the changes of load distribution in the overall network. Part 1 concludes with the presentation of the calculation tool and exemplary results. Part 2 of the paper will present the key functionality - the differentiated load mapping - as well the potential reduction of rail exchange in SBB's network. [ABSTRACT FROM AUTHOR]
