Stick-slip in stepping piezoelectric Inertia Drive Motors - Mechanism impact on a rubbing contact

Résumé

Tribology is not only science of contacts and friction. Tribologist must also take into account the mechanism dimension of rubbing contacts: vibrations propagations, damping and friction-vibration coupling. This is especially true for piezoelectric Inertia Drive Motors. IDM use the stick-slip phenomenon to make micrometric steps along a centimetric stroke. Actuation frequency - kHz - generates parasitic vibrations coupled with the overall system. This investigation aims to understand how these vibrations are created, propagate and interact. Through three experiments on a real IDM, two ways are studied: vibration damping and actuation signal modification. Better understanding of the mechanism impact leads to an energetic balance increase of 25.5%. (C) 2016 Elsevier Ltd. All rights reserved.
