Description

General framework and objectives

A Multibody System is a mechanical model of a set of bodies, also called elements or links, which can in turn be rigid or flexible, interconnected in such a way that there is relative movement between them. It is therefore a very general term that encompasses a large number of systems, among which can be mentioned mechanisms, machines, vehicles of all kinds, and robots.

The Dynamics of Multibody Systems is the theory that allows the kinematic and dynamic analysis of general mechanisms.

The dynamic optimization of multibody systems is a field that has aroused great interest in the scientific community due to the complexity of the problem and the enormous number of applications of technological development that it has in the problems of transmission of force and energy, design of mechanisms, machines and engines. However, despite the amount of resources involved, it is a discipline in a state of incipient development, with a multitude of methodologies developed for particular applications, but with a significant lack of general methods suitable for any formulation of the problem.

Nowadays, dynamic mechanisms simulation techniques are mastered, although they do not take into account influential factors such as slack, misalignments, flexibility of the elements, etc. From experience, in some practical cases it is not enough to consider perfectly guided or articulated mechanisms, obtaining deviations of up to 100%.

Therefore, it is considered appropriate to deepen the knowledge of the analysis and simulation of complex mechanisms, for the achievement of the following objective:

  • To obtain extensive knowledge in the dynamic analysis of complex multibody systems. For this purpose, the effects and parameters that intervene in them will be analysed, such as the flexibility of the pieces, the clearances in the joints, misalignments ... and thus be able to master the simulation tools that contemplate them. In this way, IK4-IKERLAN will acquire knowledge and mastery of the tools and procedures to be able to optimise complex, more energy efficient mechanisms, identify critical points, analyse the wear behaviour, help predictive maintenance, establish fatigue conditions...
