Use of simulation and wear prediction to explore design improvements to the cup seal in the India Mark II/III hand pump system

Ottosson, Hans J.; Mattson, Christopher A.; Johnson, … - In: Development Engineering 7 (2022), pp. 1-9

's focus is on this cup seal and how the wear and life of the seal can be predicted. A test rig was created to evaluate and … test cup seals. From this, seal performance and the nitrile cup seal wear coefficient were found. A two-dimensional finite … element model of the seal and the pump cylinder was then developed and used to calculate the pressure distribution and wear of …

Globalisation and changes of aircraft manufacturing production/supply-chains – the case of China

Eriksson, Soren - In: International Journal of Logistics Economics and … 3 (2011) 1, pp. 70-83

The globalisation processes taking place in recent decades imply the functional integration of development, design and manufacturing. In many newly industrialising economies, such as China, one of the industries sought after is the high-technology aircraft industry. China has emerged as an...

Design of composite tidal turbine blades

Grogan, D.M.; Leen, S.B.; Kennedy, C.R.; Ó Brádaigh, C.M. - In: Renewable Energy 57 (2013) C, pp. 151-162

Tidal turbine blades are subjected to significant thrust and torsional loadings due to the high density of the seawater in which they operate. These thrust loadings lead to high bending moments at the blade root, which can prove to be a serious design constraint for these devices and can have...

Homogenisation with application to layered materials

Patrício, M.; Mattheij, R.; de With, G. - In: Mathematics and Computers in Simulation (MATCOM) 79 (2008) 3, pp. 288-305

In this paper we are concerned with the elliptic PDEs with highly oscillating coefficients which model the behaviour of composite linear elastic materials. Analytical expressions for the effective coefficients are obtained for the case of layered materials using the theory of homogenisation....

Study of damage and repair of blades of a 300kW wind turbine

Marín, J.C.; Barroso, A.; París, F.; Cañas, J. - In: Energy 33 (2008) 7, pp. 1068-1083

The inspection of damages detected in some blades of 300kW wind turbines revealed that the nature of these damages was probably due to a fatigue mechanism. The causes that had originated the failure (superficial cracks, geometric concentrator, abrupt change of thickness) have been studied,...
