1. Numerical modelling and analysis of friction contact for turbine blades
Sammanfattning : High cycle fatigue failure of turbine and compressor blades due to resonance in the operating frequency range is one of the main problems in the design of gas turbine engines. To suppress excessive vibrations in the blades and prevent high cycle fatigue, dry friction dampers are used by the engine manufacturers. LÄS MER
2. Detection of blade icing and its influence on wind turbine vibrations
Sammanfattning : Wind turbine installations in extreme conditions like cold climate have increased over thelast few years and expected to grow in future in North America, Europe, and Asia regions due to good wind resources and land availability. Their installed capacity could reach 186 GW by the end of 2020. LÄS MER
3. Suspended forestry machines for sustainable forestry
Sammanfattning : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. LÄS MER
4. Active Lateral Secondary Suspension in a High-Speed Train to Improve Ride Comfort
Sammanfattning : Active secondary suspension in trains has been studied for a number of years, showing promising improvements in ride comfort. However, due to relatively high implementation and maintenance costs, active technology is not being used in service operation to a large extent. LÄS MER
5. Development and on-Track Tests of Active Vertical Secondary Suspension for Passenger Trains
