Concept review by the means of tolerance analysis on car powertrains
Category: Engineering
Process: Development
Introduction
The increasing variety of car programs leads to more and more cars being offered alternatively with two-wheel drive or all-wheel drive. The all-wheel alternative is equipped with an additional drive shaft for the additionally driven axle. High demands are placed on the bearings of such drive shafts. A tolerance analysis should ensure the function of an additional drive shaft for the newly to be developed power train of a premium manufacturer located in Southern Germany.
Due to the proven expert competences engineers of IndustrieHansa have been assigned.
Solution: Completion of a static 3D tolerance study considering all part and process tolerances for assembly as well as for operating status.
Puncture points
Benefits
Die Toleranzsimulation lieferte für den Kunden wertvolle Erkenntnisse für die Verbesserung des Antriebsstrangs. Die bereits in einer frühen Entwicklungsphase festgestellten Schwachstellen konnten kostengünstig und unter Einhaltung der Produktentwicklungszeit behoben werden.

Puncture points
- Set-up of a 3D tolerance simulation model on the basis of CAD data and drawings
- Verification of the tolerance data in the drawings with respect to clearness and completeness
- Monte Carlo simulation for calculation of tolerance related deviations
- Contributor calculation in order to determine relevant parameters.
- Tolerance analysis in assembly status as well as during complete motion sequence.
- Development of suggestions in order to reduce deviations Detailed documentation of simulation results
