A Co-simulation Solution for Vehicle-Track Interaction Dynamics Problems

A co-simulation solution based on direct equilibrium of contact forces is proposed to simulate vehicle-track interaction (VTI) dynamics. It is developed in two platforms, which presents an iterative feedback loop that exchanges contact force files and structure response field in real-time. The load vector acting on the structure is described by...

Design, maintain and operate movable storm surge barriers for flood risk reduction

In several coastal regions around the world, movable storm surge barriers have been implemented to protect against flooding induced by storm surges and waves. These barriers often form an integral part of the coastal defense system. In urban deltas, they are mostly intended to protect urban and industrial interests, while providing access for...

Wheel-rail dynamic interaction

A better understanding of wheel-rail dynamic interaction is necessary for the capacity increase of railway transportation. This chapter briefly introduces the consequences, modeling and detection methods of wheel-rail dynamic interaction, and maintenance of the weak track spots where wheel-rail dynamic interaction often occurs. Wheel-rail...

2.11 - Wind Turbine Reliability - Maintenance Strategies

Wind turbine technologies are evolving rapidly in terms of complexity and size and there is an urgent need for cost-effective Operations and Maintenance (O&amp;M) strategies to increase the profitability of wind power assets.<br/><br/>Component reliability as well as maintenance strategies have the greatest effect on O&amp;M planning and costs,...

Health Monitoring for Lighting Applications

Traditional lighting is focused on the prevention of hardware failures. With the trend towards controlled and connected systems, other components will start playing an equal role in the reliability of it. Here reliability needs to be replaced by availability and other modeling approaches are to be considered. System prognostics and health...

(Self) Housing Management: Challenges for Collective Densification

The development of self-organised neighbourhoods positions the residents at the centre of the process. They organise themselves to plan, densify and subsequently manage their dwellings collectively. This chapter focuses on defining the type of management that accompanies the housing densification in condominium tenure, and the challenges related...

Automating Contextualized Maintenance Documentation

Currently, task support information in aircraft maintenance is mostly provided using paper-based solutions, which are burdensome, slow and prone to error. Aircraft maintenance documentation contains vast amounts of information irrelevant for the task at hand and even for the simplest tasks multiple documents need to be consulted. Next to these...
