1. 1. Module property verification : A method to plan and perform quality verifications in modular architectures

   Författare :Patrik Kenger; Mauro Onori; Christoph Hanisch; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modular products; product architecture; product verification; test; inspection; product assembly; defects; Manufacturing engineering; Produktionsteknik;

   Sammanfattning : Modular product architectures have generated numerous benefits for companies in terms of cost, lead-time and quality. The defined interfaces and the module’s properties decrease the effort to develop new product variants, and provide an opportunity to perform parallel tasks in design, manufacturing and assembly.

3. 2. Computational Methods for Design, Planning and Verification regarding Deformable 1D Objects

   Författare :Tomas Hermansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; production planning; simulation of deformable 1D objects; variation analysis; non-linear optimization; path planning; assembly verification; routing design;

   Sammanfattning : The industry of today is focused on using virtual tools in the realization of new products. As late changes in a design and planning concept can be extremely costly, there are many benefits to discovering and addressing problems as early as possible: fewer iterations between the different product realization phases and shorter lead-times, reduced numbers of physical prototypes and test series, fewer on-line adjustments in the production system and, in the end, a product of a higher quality.

4. 3. Pilot Production and Manufacturing Start-up in the Automotive Industry. Principles for Improved Performance

   Författare :Henrik Almgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; disturbance control; performance; verification; manufacturing start-up; learning; pilot production; Swedish automotive industry; product and production preparation;

   Sammanfattning : The dissertation is based on experiences from Volvo Car Corporation and examines pilot production and manufacturing start-up, processes that are here combined under the rubric final verification of product and production system. The purpose of this dissertation is to study pilot production and manufacturing start-up in order, first, to identify and analyze factors affecting final verification performance and, secondly, to develop general principles for how final verification performance can be improved.

5. 4. Computational Methods for Deformable 1D Objects in Virtual Product Realization

   Författare :Tomas Hermansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly verification; variation simulation; robust design; path planning; Cosserat rod theory; deformable 1D objects; automatic routing;

   Sammanfattning : In industry today, virtual design tools are used in the realization of a new product. As changes in the design and planning concepts are extremely costly in the later verification and production phases, much can be gained if a product design can be optimized and verified with respect to the assembly process with simulation tools as early as possible.

7. 5. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

   Författare :Ilker Erdem; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; design; fixture; assembly; manufacturing; efficiency; flexible; production;

   Sammanfattning : The manufacturing industries have been using flexible production technologies to meet the demand for customisation. As a part of production, fixtures have remained limited to dedicated technologies, even though numerous flexible fixtures have been studied and proposed by both academia and industry. LÄS MER
