Moritz Trippe is a research assistant in the Gear Department of the Laboratory of Machine Tools and Production Engineering (WZL) of RWTH Aachen University and the group leader of the gear power density group. His research focus is the load carrying capacity of the tooth root and the influence of dynamics on the gear load capacity. Trippe studied mechanical engineering at RWTH Aachen University and has a master´s degree in automotive engineering and transport.
Aircraft engines can be made more efficient by integrating planetary gears. In such an application, the planetary gears experience very high load cycles under fully reversed bending loads. Pulsator test rigs, which nowadays offer the possibility to perform UHCF investigations, can only be used for purely pulsating loading of gears. Therefore, for the investigation of the UHCF tooth root load carrying capacity under fully reversed bending load, a back-to-back test rig is required. Back-to-back test rigs usually have speeds of n = 3,000 rpm, which makes investigations in the UHCF range take a very long time. Therefore, a high-speed back-to-back test rig was developed.
