Lightening and Innovating transmission for improving Vehicle: Environmental Impacts

The LIVE-I project tackles long-standing noise, vibration, and harshness (NVH) issues in automotive transmissions, crucial for vehicle performance, passenger comfort, and safety. With the rise of electric and hybrid vehicles, reducing NVH levels becomes paramount for driving experience and technology adoption. The project's objectives encompass four key areas: 1. Developing Advanced Models and Digital Twins: By leveraging simulation techniques and data-driven approaches, the project aims to enhance transmission design and optimization, leading to quieter and more efficient vehicles. 2. Proposing Innovative Solutions and Materials: Exploring novel materials and design strategies, the project targets lightweighting transmissions without compromising performance, contributing to sustainability and fuel efficiency. 3. Implementing Active Vibration Control (AVC) and Optimization Techniques: Integrating advanced control algorithms and sensing technologies, the project seeks to actively reduce vibrations and noise levels in real-time, enhancing vehicle comfort and performance. 4. Developing Methodologies for Future Transmissions Development: Documenting findings and insights to foster competitiveness in the European automotive industry and support the transition to a decarbonized economy. The project's interdisciplinary efforts have advanced gear transmission systems and addressed NVH challenges comprehensively. From meticulous design methodologies to innovative solutions like semi-active vibration control using MR materials, the project has pushed the boundaries of gear design and NVH control. Moreover, it has explored practical applications of metamaterials, introduced traction motors as vibration control actuators, and developed a single-stage test rig for practical experimentation. In conclusion, the LIVE-I Project illustrates collaborative research aimed at driving the automotive industry towards efficiency, sustainability, and technological excellence. Its findings provide a foundation for future research and implementation of advanced technologies in gear design, NVH control, and clean vehicle initiatives.

Project objective

For several decades, vehicles have seen their weight increase to meet more demanding requirements of safety and comfort. At the present time, manufacturers need drastically reduce the 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 in this hot topic. The technical objective of LIVE-I project is to demonstrate 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. Numerical simulations and experiments will be carried out to validate the solutions. In addition to the described technical approaches a tight integration of the individual ESRs into the overall research program is taken care of and a specific training plan devoted to their up to date education in gearboxes design and optimization is offered.
