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

   Author : Lars H. Ivarsson; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Measurement and Application of Multidirectional Mobilities

   Author : Michael A. Sanderson; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

5. 3. The Concept of Mobile Manufacturing

   Author : Carin Stillström; Jönköping University; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Supporting the Design of Reconfigurable Production Systems

   Author : Carin Rösiö; Mats Jackson; Kristina Säfsten; Erik Sundin; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; production system; manufacturing system; design process; industrialization; reconfigurability; reconfigurable manufacturing system; RMS; mobility; case study; manufacturing industry; Innovation and Design; innovation och design;

   Abstract : To compete, manufacturing companies need production systems that quickly can respond to changes. To handle change drivers such as volume variations or new product variants, reconfigurability is advocated as a competitive means. READ MORE

7. 5. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

   Author : Penka Dinkova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

   Abstract : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available. READ MORE
