Christian Westphal has been the leader of the Gearbox NVH Group at the Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University since April 2022. His research focuses on the design and the dynamic operational behavior of planetary gearboxes. Westphal graduated from RWTH Aachen University with a master’s degree in industrial engineering and management with a major in automotive engineering and corporate development.
The article proposes a method to optimize cylindrical gearbox tolerances by balancing gear noise performance and manufacturing costs using modeling, analysis, and meta-model-based optimization.
The objective of this paper is to develop a method for the algorithm-based design and optimization of the macrogeometry of stepped planetary gear stages.
