Le suivi de version du code source<\/strong><\/p>\n

Pr\u00e9sent\u00e9 par F.Salomez<\/span><\/a>, \u00e9quipe EP<\/p>\n

Le code source est partout que ce soit pour tracer des courbes, d\u00e9pouiller des mesures, simuler une machine\u2026 Mais comment organiser les diff\u00e9rentes versions de ce code ? Comment revenir \u00e0 une version stable en cas de p\u00e9pins ? Comment d\u00e9velopper de nouvelles fonctionnalit\u00e9s sans tout casser ? Si vous vous \u00eates d\u00e9j\u00e0 pos\u00e9 ces questions, nous vous invitons au s\u00e9minaire sur la gestion du code source avec Git. Dans ce s\u00e9minaire nous verrons ensemble pourquoi le suivi de version est important, quels sont les outils pour le mettre en place, et comment les utiliser au quotidien dans la recherche. Restez aussi le temps d\u2019un \u00e9change pour discuter autour de vos pratiques et des solutions que vous avez mis en place.<\/p>\n

Source code version control<\/strong><\/p>\n

Presented by F.Salomez<\/span><\/a>, EP team<\/p>\n

The source code is everywhere: curves plotting, measurements studying, machine simulation\u2026 How do we organize code versions? How to roll back to a working state in case of problems? How to develop new features while keeping a stable version? If you have asked yourself these questions, we invite you to this seminar on version control system, and in particular the usage of the tool Git. We will see why version control is important, the dedicated tools, and how to use them daily in your research workflow. Stay at the end of the seminar for a discussion about your workflow, and the solutions you are already using to tackle the problem of versioning.<\/p>\n

Etude et mod\u00e9lisation de l\u2019effet du compactage des circuits magn\u00e9tiques des machines \u00e9lectriques sur leur performance.<\/strong><\/p>\n

Pr\u00e9sent\u00e9 par H. Helbling<\/span><\/a>, \u00e9quipe OMN<\/p>\n

Il existe encore des \u00e9carts significatifs entre les pertes fer estim\u00e9es \u00e0 partir des mod\u00e8les existants et celles mesur\u00e9es en pratique. Ce s\u00e9minaire traite de l\u2019effet du compactage des circuits magn\u00e9tique de machines \u00e9lectriques de fortes puissances sur leurs propri\u00e9t\u00e9s et leurs performances. Ces derniers sont g\u00e9n\u00e9ralement assembl\u00e9s en empilant et en maintenant sous pression plusieurs paquets de t\u00f4les s\u00e9par\u00e9s par des intercalaires jouant le r\u00f4le d\u2019\u00e9vents pour refroidir la machine. Les maquettes exp\u00e9rimentales d\u00e9velopp\u00e9es et les r\u00e9sultats obtenus concernant l\u2019effet du compactage sur les propri\u00e9t\u00e9s magn\u00e9tiques (loi de comportement B(H), pertes fer) seront pr\u00e9sent\u00e9s. On pr\u00e9sentera \u00e9galement les mod\u00e8les magn\u00e9to-m\u00e9caniques d\u00e9velopp\u00e9s et leurs validations \u00e0 travers un couplage entre les logiciels de calculs par \u00e9l\u00e9ments finis Abaqus (calculs de champs de contraintes) et Code_Carmel. Quelques notions sur le magn\u00e9tisme seront \u00e9galement introduites en d\u00e9but de pr\u00e9sentation.<\/p>\n

Study and modeling of the effect of compaction of magnetic circuits of electric machines on their performance<\/strong><\/p>\n

Presented by H. Helbling<\/span><\/a>, OMN team<\/p>\n

There still exist differences between the expected losses obtained from material models used in the design of the machines and those measured on the manufactured ones. This seminar deals with the effect of compaction of the magnetic circuits of high power electrical machines on their properties and performance. In the case of large generators, the magnetic circuit is constituted of several stacks separated by airvents that are pressed together in the thickness direction of the laminations The experimental models developed and the obtained results concerning the effect of compaction on the magnetic properties (constitutive law B(H), iron losses) will be presented. We will also present the magneto-mechanical models developed and their validations through a coupling between the finite element computations software Abaqus (computations of stress fields) and Code_Carmel. Some notions on magnetism will also be introduced at the beginning of the presentation.<\/p>\n","protected":false},"excerpt":{"rendered":"
