This project addresses all production machine sectors (e.g. machine tools, agricultural machines, textile machines). Design approaches for these machines, which are currently performance and capacity driven, have to evolve to approaches where resource efficiency is optimized. To do so, energy efficiency has to be taken into account as a key parameter in the design process.The main goal of the ESTOMAD project is to develop a methodology and related ICT tools to model, simulate, analyze and optimize energy flows and losses throughout the whole machine. When optimising machine designs, interaction with suppliers is indispensable for getting up-to-date component data. Supporting this interaction is therefore a key aspect of the ESTOMAD goals. To guarantee quick take-up, the methodology will be embedded in an existing, widely used machine design software.Starting from a methodology specification, developments will be made towards multi-domain energy descriptions on different levels. In parallel, a framework will be developed for machine designers to interact with their supplier on energy considerations. Specific tests and measurements will be conducted on a number of benchmarks for verification purposes. Availability of these benchmarks allows for an extended dissemination of project results to the wide machine production sector. After embedding the ESTOMAD methodology on the existing software a number of demonstrators will be realized.The methodology will constitute a useful base for realizing regulations on energy consumption that are under development for many products, including production machinery (EUP directive).Realizing these goals requires a multi-disciplinary team with strong industrial involvement from various applications. The team is composed of two industry-oriented and one basic-research oriented research organization, one SME, three leading manufacturers active in different sectors and a provider of machine design software tools.
