Description: IINNPACTO 2011 – ARTEFAT (DEVELOPMENT OF NEW JOINT ELASTOMER DESIGNS AND FORMULATIONS VEHICLE SUSPENSION ELASTICS WITH INCREASED FATIGUE RESISTANCE (ARTEFAT). File number: IPT-2011-2030-370000. Award date: 12/21/2011. Dates of execution: 05/05/2011 – 12/31/2013.
In the current state of the development of elastomeric anti-vibration components is being developed in use predictive models to determine the most important functional characteristics (mainly its stiffness and degree of damping ) but there is not yet a model that allows to estimate quantitatively, the life that this component will have in the face of the application of a given state of charge.
Therefore, it is of the utmost urgency and interest in having a methodology for calculating and forecasting the fatigue behavior to adapt the design of a component from the early stages of development to the durability requirements.
Unexpected failure in the requirements of life is a critical developmental priority. For the special characteristics of elastomers whose behavior is non-toxic and non-toxic linear and dependent on the environmental conditions and variables with the There is currently no universal software or method to measure the time, either. analysis and life prediction.
Each company develops its own models and methodologies. Caucho Metal Productos II, S.L. (CMP), company project leader, is obliged to equip herself with a methodology and predictive models based on the characteristics of their own rubber formulations and their design and manufacturing processes.
The general objective of this project is the improvement of the durability of the elements The anti-vibration mounts incorporated in automobile suspension systems. The specific objectives are as follows: Development of methodologies for the experimental characterization of the fatigue properties of elastomeric materials as well as the fatigue resistance properties of of the durability characteristics at the component level. Development and implementation of a methodology for the prediction of results-based durability of vibration-damping components with an accuracy equivalent to the ranges of variation of the experimental of characteristics usually used in the automotive industry. Application of advanced experimental techniques, based on the in the digital image correlation method (Digital Image Correlation-DIC) and DMTA, for accelerated execution and processing of experimental results. Analysis of the influence of the parameters involved in the design of product and manufacturing process on the mechanical characteristics of the product. product. Incorporate new design criteria into the knowledge of CMPs and ITAs. product and process to obtain an increase in fatigue performances of the elastic joints. Based on the results and The experiences of this project are expected to result in modifications to the CMP design criteria and guidelines and new elastomer formulations fatigue resistant for the specific application of elastic suspension joints .
