Periodic Reporting for period 1 - LIVE-I (Lightening and Innovating transmission for improving Vehicle: Environmental Impacts)
Période du rapport: 2020-03-01 au 2022-02-28
For several decades, vehicles have seen their weight increase to meet more demanding requirements of safety and comfort. At the present time, manufacturers need to drastically reduce energy consumption and greenhouse gas emissions without sacrificing any safety or comfort. Each vehicle element must be considered for weight reduction. In this regard, gear transmissions are a first choice candidate. They form a reliable, versatile, and efficient way to transfer power while representing a significant fraction of the vehicle’s mass.
LIVE-I project main objective is to achieve breakthrough technological progress in the design of lightweight gear transmission and to build an innovative training network in order to educate early stage researchers.
The technical objective of LIVE-I project aims at demonstrating a significant weight reduction of transmission using advanced modeling tools and digital twins together with advanced materials and systems.
This objective will be pursued along different ways, each starting with mass reduction and exploring ways to achieve compromises between weight, efficiency, noise and vibration impacts. The modeling will cope with physical complexities of the problem, connected to non-linearities, multi-scale character among others.
The weight/NVH (Noise, Vibration, Harshness) and efficiency improvements of gear transmissions will be tackled by introducing new paradigms in the design of housing and components, using new meta-materials and meta-structures, studying the robustness of a given optimization with respect to real manufacturing conditions, developing smart concepts in accordance with vibroacoustic comfort.

The period covered by this first periodic report is 1/03/2020 - 28/02/2022. The period from March to August was devoted to recruitment. The selected ESRs were notified as soon as possible to start the administrative recruitment process at the level of the recruiting universities. The ESRs took up their post between October and November 2021 at their respective universities before leaving as secondment from spring 2021. This first phase of work consisted of a state of the art so that the ESRs have a good understanding of the context, issues, scientific and technological obstacles of the project. Their progress has led them to focus on their respective subjects and adopt the appropriate theoretical, numerical or experimental methods. At the end of this first phase of discovery and familiarization of the ESRs with their subjects, the ESRs went on secondments to their associated industrial beneficiary. This marks the beginning of another way of working where the ESRs had to adapt to an environment that was more industrial than academic. Certain aspects have of course been modified due to the health context. For example, some trainigs have taken place virtually and short secondments have been postponed for the moment, as long as this hinders their progress. The various members of the consortium communicated actively to organize the drafting of deliverables as well as the content of the trainings. Thanks to these numerous interactions, we are completely in phase with the milestones and the training schedule as described in the Description of the Action appendix.
The ESRs are all able to progress independently on their subject and are on track to produce results. Although a few articles are being prepared at the end of this first reporting period, these have not yet been published on the channels. The second half of the project will definitely be more oriented towards dissemination, communication and promotion activities.

The LIVE-I training program addresses strategic issues: the development of sustainable energy consumption and the de-carbonization of the economy. The methods experimented by the ESRs in LIVE-I will enable them to bring into life new methods and state of the art mechanisms in order to create lighter vehicles with more efficient energy consumption. At the end of the project, the ESRs will be fully equipped to tackle the fight against climate change through the reduction of CO2 emissions, which is one of the political priorities of the Horizon 2020 Framework program.
Impacts are expected on several aspects. First, enhancing the career perspectives and employability of researchers and contribution to their skills development. This will take the form of short and long term benefits for the ESRs. the development of technical and scientific skills, carreer management and effective communication will be regarded as immediate benefits, while networking, seeking opportunities, entrepreneurhip, skills or team management will be regarded as long term benefits.
Second, contributing to structuring doctoral/early-stage research training at the European level and to strengthening European innovation capacity. This takes the form of research excellence, attractive work environment, interdisciplinary research options, exposure to industry, international networking, soft skills trainings. The goals of the project are fully in line with the H2020 objectives to fight climate change and promote sustainable development.
Third, on the quality of the proposed measures to exploit and disseminate the results. This will take the form of dissemination of research results over the scientific and industrial network. Specifically, it will occur at academic level in the form of high-level scientific publications in open access journals, and participation to international conferences. At the technical level, participation and interactions with stakeholders and economic actors, participation to industry oriented conferences and technical workshops.
