Abstract
Programme P2-0109, entitled Modelling in technics and medicine, is connected to fields 2.11.00 Construction, 2.19.00 Traffic and 3.08.00 Medical Sciences. The programme group and its fields of research are conceived interdisciplinary and consist of researchers from Faculty of mechanical engineering, Forensic Institute, and Institute of anatomy at Faculty of Medicine, University of Ljubljana and Faculty of Chemistry and Chemical Engineering, University of Maribor. At the department of Modelling in Engineering Sciences and Medicine, the research activities are organised in Technological Centre CEMEK. In its framework operate Laboratory for Element and Structure Modelling, Laboratory Unit for traffic accident analysis and research and the Information Unit for Technical Documentation. In the field "Construction", the research group focuses its activities on special knowledge in the field of Construction of Machines and Mechanisms. Emphasis is placed on development of geometric, physical, mathematical and material numerical models of various phenomena in machine and mechanism operation, that need to be controlled in analyses of elements, groups of elements and structures (deformability, load capacity, elasto-plastic material response, material damage growth, life expectancy) and in numerical simulations of machine and mechanism operation. Additionally, we study experimental methods generally and adapt and develop methods, procedures, experimental devices and systems for model verification, in laboratory conditions as well as in the field. Research activities are devoted also to the research of acquisition and flow of information inside of development oriented enterprises. The result of research is represented in a technical documentation model, which is the basis for the definition of the information system and automation of processes in development and production preparation phases. Sphere of activity, additionally encompasses harmonization of technical documentation with current legislation, adaptation of CAE tools and technical information systems to specific needs of interested enterprises. In the field "Traffic", the research group is devoted to development and implementation of software tools for traffic accident analyses and simulations. Emphasis is placed on development of geometric and mechanical models of vehicles and human body, development of virtual 3D environment representation tools and to connecting all these pieces into general and specialized systems for traffic situation analyses. The field of work incorporates development and maintenance of experimental systems for vehicle properties determination, riding surface properties determination and development of a system for measurement and analysis of human body response in traffic accidents. Research results of the program group are software applications and expert valuations. In the field "Medical Sciences", the research group is involved with determination of influences that mechanical loads on human body, have on injury development. A narrower research field inside this field is "collision biomechanics". By measuring the response of human body in vehicle crash conditions it is possible to determine the influence of various individually dependent factors on loads and injuries to particular anatomical body parts of the vehicle occupant. Based on data, obtained from measurements, numerical models of human body are developed, that can be used for analysis and prediction of injuries in traffic accidents. The principles of geometric and mechanical modelling are also used by the individual members of the programme-group in development of applications for virtual simulations of various surgical operations.
Significance for science
The proposed research programme focusing on the carrying capacity and durability of machine elements and assemblies integrates well into the recent research trends in this field of mechanical engineering, according to which the carrying capacity and duration of elements are determined through real load conditions, non-linear deformation-strain response and continuum damage mechanics. The finds and the results arising from the research supplement the findings obtained in similar fields of operational strength, fracture mechanics and tribology. Future research is expected to focus on: a. modelling the performance of material (steel) which is exposed to loads and subjected to initiation and propagation of damage in the low-cycle domain and at impulse loads, b. methods for experimental and numerical determination of low-cycle parameters of steel, c. experimental methods for detecting the initiation and propagation of material damage and damage diagnostics in large rolling bearings, and d. generation of an improved finite element code and its integration into the commercial FEM analysis program that permits calculations at the global structure level. Mathematical models used to describe vehicle motion and passenger motion are derived on the basis of various mechanical models of multi body systems and as such provide a means for concurrent vehicle drive and ride dynamics analyses. Expected further development of knowledge includes: a. development of programme solutions for interactive simulation and the display of mechanical systems motion in real time, b. stability analyses of nonlinear differential equation solutions, c. development of 3D mathematical modelling of multibody system dynamics. Furthermore, progress is expected in biomechanics and medicine, in particular with regard to the following: a. development and verification processes in human body modelling in consideration of individual human body features (build, age, sex), b. preparation of test items in determining the mechanical and material characteristics of anatomic structures and in determining dynamic responses of human bodies in crash conditions, c. characterization of tissue, damage mechanisms and critical mechanical loads.
Significance for the country
A) For sustainable socio-economic and cultural development: a. faster and more accurate handling of claims arising from road accidents at the courts of the Republic of Slovenia (RS), b. supplementation of the accident and motor vehicle insurance in the RS, c. establishing databases and GIS to improve road safety, d. preparation of regulations governing safety at work, traffic regulations, etc. B) For technological development – the results of research programme can be used in: a. traffic (traffic flow simulation, identification of critical road sections, etc.), b. administration of justice (top-quality expert opinions in engineering sciences and medicine), c. insurance industry (verification of the eligibility of claims for loss on vehicles and vehicle users), d. civil engineering works (control of project compliance with the actual roadway, ride dynamics in individual sections, roadway signalisation, etc.), e. sports (body loading in extreme sports), f. medicine (load simulations in various types of injuries), g. army (selection and design of terrain vehicles for the existing infrastructure, driving simulators, analyses of crew, vehicle and weapon load in combat operations, etc.) and h. mechanical engineering (advanced methods for structure and element evaluation, development of vehicles and mobile technology, new test stands and testing and control methods, etc.
