Abstract
The research programme can be divided into two areas of priority, the first one being modelling of machine elements, assemblies and complete designs with an emphasis on rolling rotational connections, and the second one being the modelling of road-traffic accidents, including kinematics and driving dynamics of vehicles and passengers through all the accident phases. In addition to this, the research group performs activities considering acceptation of Slovenian standards in the field of technical documentation along with providing technical support, consulting and education.
The focus in the first field of research is carrying capacity of rolling contacts regarding two-layered structure (hard surface – softer core) of materials and low-cycle load characteristic. The results of this research are carrying criteria of contacts between roller elements and raceway in large rolling bearings. In modelling static and low-cycle carrying capacity as well as the life time of large rolling bearings used for combined loads, we investigate the influence of the structure (elasticity) of carrying constructions (support, superstructure) on the distribution of external load in elements of rolling connections. This is the base for the development of models for computing carrying limits and rolling resistance in various combinations of external loads and different operation conditions. The acquired knowledge in this field is intended to be experimentally verified and built into an expert system for rotational connection design.
The second area of research is about completion of mathematical models and algorithms, which are the base for the development of software for road-traffic accident analysis. The projects and other activities in this field are co-ordinated within the EU. The research group co-operates in devising algorithms for analysis of driving kinematics, collisions in 3D space regarding the elasticity of vehicles (the new approximative model) and models for simulation of driving in 3D space. The group is highly active in the field of dynamic analysis of human body and in determining and computing injury criteria. For a road vehicle and for human body, a mechanical model with finite number of rigid and elastic bodies, bound with different type of joints, is being developed. We intend to experimentally verify the efficiency of the described method, the rules of driving dynamics and vehicle handling, the mechanical properties and geometrical and inertial properties of various parts of human body.
