Researchers at the\u00a0International Centre for Numerical Methods in Engineering<\/a>\u00a0(CIMNE) have proposed novel material solutions based on high-strength steels, composites and hybrid materials to\u00a0reduce the weight of electric car chassis components by 40%<\/strong>.<\/p>\n

The research was conducted as part of the\u00a0European project\u00a0<\/strong>Fatigue4Light<\/a><\/strong>, focused on researching new materials for zero-emission vehicle chassis while ensuring good fatigue performance. Experts obtained the\u00a0best results in steels of high mechanical resistance<\/strong>, which, according to the study carried out, offer excellent mechanical behavior with the least impact on carbon footprint.<\/p>\n

Despite the positive results, researchers at\u00a0CIMNE’s Composites and Advanced Materials for Multifunctional Structures<\/a><\/strong>\u00a0research group<\/strong>\u00a0warn that the production of multimaterial solutions itself has a significant environmental impact.<\/p>\n

The analysis results were presented during the\u00a0project’s closing meeting<\/strong>, held virtually on Friday, where project partners shared their research findings.<\/p>\n

Over three years, researchers from four countries, led by CIMNE, developed\u00a0new methods of rapid experimental analysis and computational fatigue simulation<\/strong>\u00a0to estimate the life of chassis components subject to wear and selected optimal materials for weight optimisation.<\/p>\n

\"\"<\/p>\n

Started in 2021, the project was divided into four work phases. In the initial stages, experts identified new materials based on the exploration of steel, aluminium alloys, and combinations of composite materials. During the later phases, they worked on creating new virtual and experimental tools to optimize weight, validated with six laboratory and industrial-scale demonstrators.<\/p>\n

Dr.\u00a0Luc\u00eda Barbu<\/strong><\/a>, member of the Composite and Advanced Materials for Multifunctional Structures group, head of the Fatigue unit at CIMNE, and project coordinator, emphasized that the research considered\u00a0\u201ceco-design and circular economy criteria\u201d<\/strong>\u00a0to further reduce the environmental footprint of new electric vehicles.<\/p>\n

According to Dr. Barbu, the improvement of fatigue simulation computational models will\u00a0reduce the implementation time of new materials in chassis design for new vehicles<\/strong>, a \u201ccritical component\u201d that currently accounts for \u201chalf of the weight\u201d of electric cars, along with the vehicle frame.<\/p>\n

In the words of the scientific director at the Technology Centre\u00a0Eurecat<\/a><\/strong>, Daniel Casellas, the results from this project will\u00a0\u201callow for a 10% reduction in the development of new chassis components for electric cars\u201d<\/strong>. The results will also bring \u201cnew solutions\u201d to reduce the chassis weight \u201cup to 40%,\u00a0using sustainable materials, such as high-strength steels<\/strong>\u201d.<\/p>\n

These solutions can be applied in other industrial sectors \u201cthat use components subjected to cyclic loads, such as the railway sector or renewable energies\u201d.<\/p>\n

The Fatigue4Light project involved\u00a0three universities and research centres<\/strong>, six companies from the sector, and a regulatory body:\u00a0Centro Ricerche Fiat<\/a>,\u00a0Lule\u00e5 University of Technology<\/a>,\u00a0CLN Group<\/a>,\u00a0Profilglass<\/a>,\u00a0RISE – Research Institutes of Sweden<\/a>,\u00a0Politecnico di Torino<\/a>,\u00a0CIEFMA – Center for Research in Structural Integrity, Reliability and Micromechanics of Materials at the Technical University of Catalonia<\/a>\u00a0(UPC),\u00a0Gestamp<\/a>,\u00a0UNE – Asociaci\u00f3n Espa\u00f1ola de Normalizaci\u00f3n<\/a>,\u00a0ArcelorMittal<\/a>,\u00a0Eurecat – Technology Centre of Catalonia<\/a>, and\u00a0CIMNE<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
