Stochastic model for lubricating film thickness in rolling contact
No full textOn-line monitoring plays an important role in lifetime management of machinery. An especially interesting element of machinery is oil – as a lubricant or hydraulic fluid. The present paper introduces a model that has been developed for evaluating film thickness in rolling contact based on parameters such as viscosity, water content of lubricant, temperature, pressure and rolling versus sliding ratio. After combining direct or indirect information from different sources, statements can be made concerning machinery and the condition of its components. These statements are used in maintenance and replacements decisions, in order to avoid failures leading to unexpected unavailability and to optimise overall costs. Here, a mathematical modelling framework for combining various condition monitoring measurements to predict or estimate the lubricating oil film thickness is presented. The approach is based on stochastic filtering principles

No full textThe Finnish Nuclear Power Plant Safety Research Programme 2011-2014, SAFIR2014, is a 4-year publicly funded national technical and scientific research programme on the safety of nuclear power plants. The programme is funded by the State Nuclear Waste Management Fund (VYR), as well as other key organisations operating in the area of nuclear energy. The programme provides the necessary conditions for retaining knowledge needed for ensuring the continuance of safe use of nuclear power, for developing new know-how and for participation in international co-operation. The SAFIR2014 Steering Group, responsible of the strategic alignments of the programme, consists of representatives of the Finnish Nuclear Safety Authority (STUK), Ministry of Employment and the Economy (MEE), Technical Research Centre of Finland (VTT), Teollisuuden Voima Oyj (TVO), Fortum Power and Heat Oy (Fortum), Fennovoima Oy, Lappeenranta University of Technology (LUT), Aalto University (Aalto), Finnish Funding Agency for Technology and Innovation (Tekes), Finnish Institution of Occupational Health (TTL) and the Swedish Radiation Safety Authority (SSM). The research programme is divided into nine areas: Man, organisation and society, Automation and control room, Fuel research and reactor analysis, Thermal hydraulics, Severe accidents, Structural safety of reactor circuits, Construction safety, Probabilistic risk analysis (PRA), and Development of research infrastructure. A reference group is assigned to each of these areas to respond for the strategic planning and to supervise the projects in its respective field. Research projects are selected annually based on a public call for proposals. Most of the projects are planned for the entire duration of the programme, but there can also be shorter one- or two-year projects. The annual volume of the SAFIR2014 programme in 2011-2012 has been 9,5-9,9 M . Main funding organisations were the State Nuclear Waste Management Fund (VYR) with over 5 M and VTT with nearly 3 M annually. In 2011 research was carried out in 38 projects, and in 2012 the number of research projects was 42. The research in SAFIR2014 has been carried out primarily by VTT. Other research organisations involved in research activities are Lappeenranta University of Technology, Aalto University, Finnish Institution of Occupational Health, Finnish Meteorological Institute, Finnish Software Measurement Association FiSMA, Fortum Power and Heat Oy, and Helsinki University. In addition, some subcontractors have contributed to the work in some projects. This report gives an overview of the SAFIR2014 programme and a summary of the scientific and technical results of the research activities in 2011-2012
