Abstract
The development of computing technology in the last decades has led to the emergence of a wide variety of methodologies aiming at reducing the costs of design, manufacturing and maintenance stages of products during their life cycle. Out of these three phases, maintenance has proved to have the biggest impact in most industrial contexts both in terms of energy consumption and economical costs. For this reason, the proposal of different techniques that allow an accurate simulation of the working conditions of mechanical systems and an early detection of any possible faults that can arise is of interest to researchers and industry.
In this thesis, special attention is paid to the definition of computational modelling methodologies based on multibody dynamics which can be used as digital twins, which allow the virtualization of certain conditions of the real system, thus playing an important role in the early identification of potential issues, prediction of failures, and optimization of maintenance processes of industrial systems.
Emphasis will be placed on the modelling of systems in which multiple contact events take place simultaneously, which is a trending and challenging research topic. In this regard, a comprehensive review of the existing methodologies is carried out. Then, an in-house code will be used to test the proposed algorithms by using a simple validation application. The conclusions obtained will subsequently be applied to the simulation of mechanical elements in working conditions.
The results obtained are consistent with those available in the literature, both theoretical and experimental, and set a wide variety of paths for future research lines.
