Performance enhancement of Harmonic Drives through tooth profile optimisation

Institute for Mechatronic Systemes in Mechanical Engineering

Masterthesis

At VIAME, we are developing new concepts for lightweight design in several sectors (transportation, energy, machining,…). This research project will be focused on detailed investigations on the tooth profile, Regarding influence of tooth profile parameters on harmonic drive performance, not only macro parameters but also micro parameters, such as surface roughness and contact geometry of the tooth on lubrication will be considered. More specifically, a detailed model for harmonic drive will be established, considering factors of lubrication, relative velocity, meshing point load, tooth contact geometry and surface roughness, etc. Based on design of various harmonic drive prototypes, tooth profile modifications and their impact will be evaluated with both simulations and additional experiments The thesis will be performed remotely at Ecole Central de Lyon, France.
