1. 1. Measurement and Application of Multidirectional Mobilities

   Författare :Michael A. Sanderson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source signal filtering; mass loading; rotational mobility; rotational inertia loading; multidirectional mechanical mobility; moment mobility; structural intensity; measurement techniques; vibration isolation;

   Sammanfattning : The direct measurement of moment mobility, employing a twin exciter technique, is theoretically and experimentally examined. This is continued by a theoretical and experimental analysis of an improved technique using source signal filtering, for two degrees of freedom, for the measurement of multidirectional mobilities.

3. 2. Multidirectional Mobilities - Advanced Measurement Techniques and Applications

   Författare :Lars H. Ivarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; R-DOFs; substructuring; measurement techniques; rotational mobility; multidirectional mechanical mobility; hybrid coupling; coupling; moment mobility; impedance coupling; consistency;

   Sammanfattning : Today high noise-and-vibration comfort has become a quality sign of products in sectors such as the automotive industry, aircraft, components, households and manufacturing. Consequently, already in the design phase of products, tools are required to predict the final vibration and noise levels. LÄS MER

4. 3. Recharging Future Mobility : Understanding Digital Anticipatory UX through Car Ethnographies

   Författare :Thomas Lindgren; Vaike Fors; Magnus Bergquist; Martin Berg; Robert Broström; Marc Hassenzahl; Högskolan i Halmstad; []

   Sammanfattning : Cars have created many positive experiences for people by providing them freedom of mobility, exciting driving thrills and status in society. However, cars are also known to create problems such as pollution, traffic congestion and accidents. LÄS MER

5. 4. The Concept of Mobile Manufacturing

   Författare :Carin Stillström; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; flexibility; changeability; manufacturing system; production system; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi; Manufacturing engineering and work sciences; Produktion och arbetsvetenskap;

   Sammanfattning : There is a need for a manufacturing concept that is characterized by ease in changing between manufacturing places, ease in producing wherever it is convenient for the moment, ease in collaborating with different partners, and reconfigurability and reuse of manufacturing capacity, while at the same time keeping control of the own capabilities. The objective of this thesis is to investigate and describe the concept of mobile manufacturing in order to find new ways of competing for the manufacturing industry. LÄS MER

7. 5. The Robustness and Energy Evaluation of a Linear Quadratic Regulator for a Rehabilitation Hip Exoskeleton

   Författare :Rabé Andersson; Niclas Björsell; Daniel Rönnow; Gianni Borghesan; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hip Rehabilitation Exoskeleton; Robust Controller; Energy Consumption; Series Elastic Actuator SEA ; LQR Control; Luenberger State Observer; Torque Control; Höftexoskelett för rehabilitering; Robust reglering; Energiförbrukning; serieelastiskt manöverdon SEA ; LQR reglering; Luenberger State Obser-ver; Moment reglering;

   Sammanfattning : The implications of gait disorder, muscle weakness, and spinal cord injuries for work and age-related mobility degradation have increased the need for rehabilitation exoskeletons. Specifically, the hip rehabilitation exoskeletons due to a high percentage of the mechanical power is generated by this join during the gait cycle. LÄS MER
