5. 9. Increased precision in variation simulation by considering effects from temperature and heat

   Författare :Samuel C Lorin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat; robust design; temperature; Varition simulation; welding simulation;

   Sammanfattning : Every manufactured product deviates from the intended product. In a production series a number of noise sources will influence the product resulting in geometric variation. This variation leads to functional and aesthetical variation of the product. LÄS MER

7. 10. Variation Control in Virtual Product Realization - A Statistical Approach

   Författare :Kristina Wärmefjord; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quality control; contact modeling; Variation simulation; welding simulation; spot welding sequence; inspection point reduction; fixture repeatability;

   Sammanfattning : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. LÄS MER
