Simulation of mechanical systems

02.09.2005


Assistant lecturer at the Public University of Navarra, José Javier Gil Soto, is the author of the thesis “Preprocesser for dynamic simulation of multibody systems based on symbolic algebra”. The work undertakes the conceptual development and subsequent implementation of a symbolic system that enables the putting forward and resolution, in a simple manner, of the most common problems in classical mechanics.



Simulation techniques

The study undertaken by José Javier Gil Soto centred on the simulation of mechanical systems. The thesis begins with a review of the literature on the subject and then there is a description of the implementation of a symbolic language, based on the MatLab-Maple symbolic engine, specific to DSM. MatLab is a matricial and symbolic calculus programme. We chose this because, from the users’ point of view, it had a number of advantages compared to other programming languages. The developed tool enables the user to put forward dynamic equations for a mechanical system in a symbolic manner and subsequently resolve them numerically.


The developed symbolic system enables the definition of the Multisolid system on three levels of abstraction that are different to and compatible with each other. Moreover, it has libraries for exporting to other languages and numerical templates aimed at the resolution of typical DSM problems.

The advantage provided by this algebraic system is, given its symbolic character, it is independent of the type of co-ordinates used. Thus, the set of dynamic equations obtained is more compact and suitable for the simulation of, for example, dynamic systems in real time.

The design of a fork-lift truck

Although the aim of the thesis was the development of dynamic models for rigid solid systems, the philosophy of its implementation means that the proposed thesis can be easily extended to combined rigid-flexible systems.

The implemented system can also be applied in the real time simulation of dynamic systems. In this regard, the research team at the Public University of Navarra is currently working with 3D_Mec-MatLab to develop a dynamic model for a fork-lift truck that interacts with a virtual reality system. In this case, the dynamic model has to be put forward in such a way that the dynamic equations can be resolved at the same time as the user of the virtual reality programme carries out certain operations (activating steering wheel and so on).

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
