The CONTACT software for wheel–rail contact evaluation is extended to support rails with a varying cross section. The extension involves novel tensor spline techniques for 3D geometry representation, and extension of the existing contact search methods to work on the full 3D rail geometry without resorting to a locally prismatic approximation. The resulting software is integrated in the NUCARS software for vehicle–track interaction. Results are presented for one of the recent benchmark cases on switches and crossings.

摘要

The CONTACT software for wheel–rail contact evaluation is extended to support rails with a varying cross section. The extension involves novel tensor spline techniques for 3D geometry representation, and extension of the existing contact search methods to work on the full 3D rail geometry without resorting to a locally prismatic approximation. The resulting software is integrated in the NUCARS software for vehicle–track interaction. Results are presented for one of the recent benchmark cases on switches and crossings.
