Structural Dynamic Topology Optimisation of a Direct-Drive Single Bearing Wind Turbine Generator

Reducing weight of off-shore wind turbine nacelles is currently a key driver of innovation within the wind turbine industry. Weight reduction will not only lead to smaller loads and thus smaller towers of the turbine, but also reduce logistic costs during the turbine’s installation. This holds even more so for off-shore turbines, the costs...

Thermo-Hydrodynamic Analysis of a Plain Journal Bearing on the Basis of a New Mass Conserving Cavitation Algorithm

Accurate prediction of cavitation is an important feature in hydrodynamic bearing modeling. Especially for thermo-hydrodynamic modeling, it is crucial to use a mass-conservative cavitation algorithm. This paper introduces a new mass-conserving Reynolds cavitation algorithm, which provides fast convergence and easy implementation in finite...

An apparatus for carrying and transporting a product

An apparatus for carrying and transporting a product, comprising a conveyor having a surface, which surface is during use directed towards the product and is provided with inlet openings and outlet openings for a medium for supporting and providing the product with traction, wherein the surface is divided into adjacent surface parts, and wherein...

The invention relates to an apparatus (1) for carrying and transporting a product, comprising a conveyor (2) having a surface (4) which during use is directed towards the product and is provided with inlet openings (7) and outlet openings (8) for a medium providing the product with traction, wherein the surface (4) is at least provided with...

The Hydro-Support: An Elasto-Hydrostatic Thrust Bearing with Mixed Lubrication

The "classic" solution for the support of a translating lockgate, the wheelonrail support, has relatively high construction as well as inspection and maintenance costs. An alternative support which has previously been developed for use in the Prins WillemAlexander lock is the socalled "hydrosupport", a hydrostatic thrust bearing that slides on...
