This tutorial will provide the framework required when designing mechanical systems with high immunity against thermal effects, i.e. temperature drifts and/or thermally induced elastic distortions. It will span basic and advanced concepts, practical evaluation tools and methods, as well as control strategies. A particular emphasis will be placed on the usage of an integrated approach, allowing to develop compact thermal elastic models sufficient to provide an understanding of the key parameters governing each problem. Such models can not only be used to decide on the severity of individual sources of disturbance but are also mandatory when designing practical mitigation solutions, either passive or active.
The approach will be illustrated with applications ranging from simple academic test cases and widespread components such as flexure-based translation stages, up to more advanced opto-mechanical systems.
From these examples, it will be demonstrated that the design of high-performance systems relies on a small set of concepts and rules, which can be effective for fulfilling ordinary or less conventional customers’ requests.
Intended audience: This is a beginning to intermediate level course, with material ranging from basic to complex, to provide both an overview and references for further study. The intended audience is graduates, postgraduate engineers/physicists, plus industry technical staff having a first experience in systems for which thermal stability aspects are relevant, and aiming at strengthening their insight so as to reduce guesswork for future projects.
Nicolas Jobert studied Mechanical Engineering at the Ecole Centrale Marseille, where he specialized in Noise and Vibrations. After graduating in 1996 he has been active in a range of consulting companies providing services for industry, civil engineering companies and academic research centers. During these periods, he carried out problem characterization via in the field or in the shop measurement campaigns, as well as the design and numerical simulation/validation of corrective procedures. Nicolas has also worked in a large international group on the safety of nuclear power systems, and recently at the French National Synchrotron Radiation Light Source (SOLEIL), where he contributed to the design, validation and commissioning of accelerators and beamline systems.
In 2018, he founded Alma Consulting in order to offer his services in the field of Precision Engineering.
He also teaches Master 2 classes (Université Paris-Saclay) together with specialized sessions for professionals, with an emphasis on high-precision optomechanical systems.
