Innovative DEsign for Reliable PLANEt bearings

Description
The high power transmissions that have to be designed for modern highly efficient turbofans need the extensive application of epicyclical gears with planet gear containing an integrated bearing. These components are subjected to severe rolling contact fatigue (RCF) conditions as many others (e.g. wheels/rails of high speed trains): propagation of micro-cracks starting from the bearing race surface and leading to spalling is a typical damage mode of these components. The main idea behind IDERPLANE is to analyze the problem not in terms of the usual stress-based design of gears, but rather on damage tolerance concepts. This kind of analysis is meant at understanding/measuring the risk of a catastrophic failure in the case of development of subsurface propagation of cracks driven by shear stresses. Incidentally, it has to be emphasized that spalls can lead to sub-surface cracks only once they have reached a critical size. If this could be seen an established route, unfortunately RCF is a grey area where there are no data available for such an analysis (that should be based on reliable crack growth curves), because it is very difficult to make cracks propagate under shear as it happens in RCF (and as it was shown in the known failures of planet gear containing an integrated bearing). This is the strength and unicity of the IDERPLANE consortium where the partners have special technology and abilities: to obtain crack growth curves under RCF conditions on specimens (PoliMI) ; to reproduce the subsurface crack propagation in bi-disks experiments (UniBS); to follow and track the development of cracks under complex load conditions (INSA).

The European Leader Equipment for Packaging Testing

Description
Nowadays big brand owners, packaging manufacturers and logistic companies faces losses of €50.000 million/year worldwide due to goods damages during transportation. At the same time, governments across the world are implementing rigorous guidelines to ensure quality of packed goods and safety during their delivery. Packaging testing is an integral part of these initiatives as it simulates the risk damages experienced by the packed goods (boxes, pallets or loads) during their distribution. In Europe, the European Commission has established the directive 2014/47/EU for safe shipment of goods. Next year, in 2017, this directive will force all the transport players to ensure the stability and safety of the loads from detrimental movements. In spite of the European concerns, currently in the market there is a lack of accurate and price competitive simulation equipment supporting the European goals. In the race to achieve '0 fatalities in road transport by 2050', established by 2011 Transport White Paper, we only find few American innovative technologies. Our solution is the first European tool to reproduce the transportation risks events such as drops, impacts, vibration and compression for packed goods. With TranSafeLoad we aim to launch to the market an integral solution 30% more price-competitive, with the broadest load range for packaging test simulation (from small boxes to 2 Ton loads) and able to reproduce real 3D movements, thanks to its patented mechanism. Furthermore, aligned with the environmental European regulatory D1994/62/CE for packaging waste reduction, our system will help the optimization of packaging material, reducing the extra material from the current 30% to 10% and saving at least €800 million/year.
