Journal bearings are widely used in heavy industry and in internal combustion engine applications. There is a need to increase the power density of various machine parts which leads to increased bearing loads and reduced lubrication film thicknesses. This type of development may increase deformations on the bearing surfaces which need to be considered in the bearing design process. The main purpose of this work was to develop a parameterized calculation model for hydrodynamic radial journal bearings which takes into account elastic and thermal deformations of the bearing surfaces. Hydrodynamic calculations were based on the numerical solving of the Reynolds equation by assuming rigid surfaces. Elastic and thermal deformations of the bearing and shaft surfaces were calculated by using the finite element method. It is concluded that elastic and thermal deformations are partly canceling each other out at the loaded side of the bearing and depending on the sliding speed and the external normal force either one of them could be more significant. © 2016 Trans Tech Publications, Switzerland.

In the past, customers invested in high cost, long service-life products. Today, they demand complex product-services capable of adapting to new customer goals and rapidly changing markets. The Use-it-wisely project will enable European manufacturers to operate successfully within this new paradigm. The project will investigate a new business model that implements continuous product-service adaptation through a sequence of small innovative steps. It will demonstrate that product-service agility and extended service life realized in this way is more viable than large and infrequent upgrades in terms of cost, duration and environmental impact. Use-it-wisely will develop and demonstrate the adaptation platform consisting of the following three elements: (1) multi-disciplinary actors-product-service system model; (2) adaptation mechanism based on the knowledge and skills of all actors involved with the system; (3) interactive collaborative distributed environment, where the actors work out the adaptation steps. The scientific breakthrough will be achieved by creating and validating a holistic systems engineering structure that combines human-machine systems, product lifecycle management, business and organizational dynamics and lifecycle assessment. The industry-led consortium is founded on complementary clusters in six key industry sectors: energy, machinery, space, office workplace, vehicles, and ship building. Use-it-wisely will enable new business for the manufacturers and their suppliers, subcontractors and open new opportunities for the customers. It will increase their competitive advantage by means of product-service agility, lower costs, shorter lead times, and reduced environmental impact. Finally, it will help to transform peoples knowledge and skills into product-service value thus strengthening Europes global competitiveness and securing domestic employment. With Use-it-wisely, the more the product-service is used, the better it gets.

Manual work is a crucial and expensive component of manufacturing. Globalization causes companies to reduce manual work costs by offshoring and global outsourcing. This poses problems such as increased lead times, lower quality products and services, and weaker management. Because of the pressure of globalization and the decline of the working age population in Europe, the situation will get worse in sectors with a large proportion of high value manual work that cannot be automated or outsourced. The ManuVAR project aims to provide a timely and systematic solution to this problem. The objective of ManuVAR is to develop an innovative technology platform and a framework to support high value manual work throughout the product lifecycle. ManuVAR will cover ergonomics, safety, work assistance, and training. It includes various people from designers to factory workers, operators, maintenance personnel, and end-users. The aims of ManuVAR are to: (1) increase productivity and quality, reducing the cost of high value manual work at every stage of the lifecycle; (2) facilitate adaptation to product customization and changes; (3) support efficient knowledge and skill management; (4) improve EU industry competitiveness via knowledge-based business models. This will be achieved by employing virtual reality technology to facilitate communication between people and systems. It will also enable the two-way flow of knowledge and its accumulation and reuse throughout the entire lifecycle and across subsequent system generations. The consortium comprises 18 partners representing industry, research and academia. In ManuVAR, there are five synergistic application clusters in different industrial areas: terrestrial satellite assembly, assembly line design, remote maintenance of trains, maintenance of nuclear reactors, large machine assembly process design. ManuVAR will demonstrate that high value, high knowledge manual work is an opportunity to improve the competitiveness of EU industries.

The aim of Marie Curie linking Industry to CERN (MeChanICs) is to enhance knowledge exchange in the field of precision manufacturing. The project gathers five specialised precision manufacturer companies of excellence, of which one is an SME, to enhance their existing research and technology development (RTD) efforts with the University of Helsinki (UH) and CERN. The mechanisms used for the transfer of knowledge within MeChanICs are two-way intersectoral secondments and dissemination workshops. MeChanICs will be established within the UHs existing research cooperation with the CERN-led Compact Linear Collider (CLIC) technology development, one of the highlighted topics of the European Strategy for Particle Physics. CLIC is likely to represent the forefront of Particle Physics in the post-Large Hadron Collider (LHC) era and its development boosts the competitiveness of its suppliers by pushing the used technologies to their limits. Close co-operation with industry in the next years is vital to devise an industrialisation scheme enabling the mass manufacturing of the required components at an affordable price and on time for a decision on the future direction of Particle Physics based on the LHC results. From the perspective of European industry, CLIC represents major technological challenges, possibilities for long-term RTD collaboration as well as significant future commercial opportunities, especially as CLIC technologies already show potential beyond Particle Physics applications, notably for X-ray free electron lasers and hadron therapy. The project strongly supports the on-going international RTD projects in machining and in precision assembly. MeChanICs widens the precision manufacturing value chain by also comprising RTD in brazing, materials and design. In addition, MeChanICs contributes to the objectives of the MoU between the EC and CERN on further developing the European Research Area, particularly concerning researcher training and mobility.

Crushed sand fines have a pronounced effect on fresh concrete rheological properties, which can be controlled through a concrete micro-proportioning approach, i.e. optimisation of the particle size distribution (PSD) in the very fine range of the grading (≤250 μm). The paper describes a study where possibilities of producing crushed sand by combining high-speed (70 m/s) vertical shaft impact (VSI) crushing and static air classification are explored to enable the micro-proportioning approach in full-scale aggregate and concrete production. In addition, the effect of rock resistance to fragmentation (crushability) on the shape improvement and fines generation during high-speed VSI crushing is experimentally studied. The VSI crushing experiment results show that an acceptable level of crushed sand particle (1.25-8 mm) equi-dimensionality (flakiness index lower than 5-8%) can be achieved for all processed feeds, regardless of the parent rock crushability or initial particle shape. The amount of fines smaller than 63 μm and 125 μm generated during high-speed VSI crushing is very strongly governed by the resistance to fragmentation of the processed rock materials. Analysis of the air classification results show possibilities of modelling a variety of different crushed sand fine particle (≤250 μm) grading curves independently of the rock type, amount of fines or grading of the crushed sand product after the VSI crushing. © 2015 Elsevier Ltd.

An abrasive wear analysis of the hardened surface layer in high austenitic manganese steel is presented to determine the effects of plastic strain and strain rate. The pre-deformation levels used in this study represent the typical surface layers resulting from the abrasive contact of Hadfield type steels. The effect of dynamic loading used in the pre-straining is accounted for alongside with various plastic strain levels. A friction study of the surface was included to determine the localization of work hardening and the ability of the microstructure to resist abrasion. © (2013) Trans Tech Publications.
