  1. 1. Strategies for Reducing Vibrations during Milling of Thin-walled Components

    Författare :Bertil Wanner; Cornel Mihai Nicolescu; Thomas Björk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Milling; vibrations; chatter; stability; prediction; thin-wall; Inconel 718; Manufacturing and materials engineering;

    Sammanfattning : Factors such as environmental requirements and fuel efficiency have pushed aerospace industry to develop reduced-weight engine designs and thereby light-weight and thin-walled components. As component wall thickness gets thinner and the mechanical structures weaker, the structure becomes more sensitive for vibrations during milling operations. LÄS MER

  3. 2. Controlling over-actuated road vehicles during failure conditions

    Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. LÄS MER

  4. 3. Faults and their influence on the dynamic behaviour of electric vehicles

    Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Jonas Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fault classification; vehicle dynamics; electric vehicle; failure; fault-tolerant control; reconfiguration; fault handling; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Sammanfattning : The increase of electronics in road vehicles comes along with a broad variety of possibilitiesin terms of safety, handling and comfort for the users. A rising complexityof the vehicle subsystems and components accompanies this development and has tobe managed by increased electronic control. LÄS MER

  5. 4. Change and Progress in Disaster Risk Reduction

    Författare :Maximilian S. T. Wanner; Daniel Nohrstedt; Charles F. Parker; Andreas Duit; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; public policy; sustainable development; disaster risk reduction; adaptation; international environmental agreements; soft law; regime effectiveness; Hyogo Framework for Action; Fiji; Nepal; Statskunskap; Political Science;

    Sammanfattning : Human-induced climate change is projected to increase the frequency and magnitude of natural hazard events, posing a growing global threat to lives, livelihoods, and assets. Much past research on disaster risk reduction (DRR) has focused on failures of disaster management, while less attention has been devoted to how DRR has changed or improved over time. LÄS MER
