2. 1. Towards an Effective Virtual Sheet Metal Assembly Development Process Securing Geometrical Quality and Equipment Utilization

   Author : Johan Segeborn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot motion planning; geometrical quality; equipment utilization; robust design; Sheet metal assembly; tolerance analysis;

   Abstract : Automobiles are an integral part of modern society and its way of life. In addition, automotive manufacturers are important institutions in society, summing the work of a vast array of sub suppliers, employing many. The margins are however moderate and competition is fierce. READ MORE

4. 2. Individualizing assembly processes for geometric quality improvement

   Author : Abolfazl Rezaei Aderiani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective Assembly; Individualization of production; Locator Adjustments; sheet metal assembly processes; Variation Simulations; Geometry Assurance;

   Abstract : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it usually increases production costs. READ MORE

5. 3. Variation simulation of sheet metal assemblies for geometrical quality : parameter modeling and analysis

   Author : Stefan Dahlström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerancing; geometrical variation; variation simulation; sheet metal assembly; virtual verification; geometrical quality;

   Abstract : The automotive industry deals with an increased demand for virtual verification of the geometrical quality of the product. The aim is to reduce the need for adjusting the assembly process to deliver a product with high quality. READ MORE

7. 5. Finite Element Analysis of Sheet Metal Assemblies : Prediction of Product Performance Considering the Manufacturing Process

   Author : Alexander Govik; Larsgunnar Nilsson; Ramin Moshfegh; Mats Oldenburg; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis concerns the development of methodologies to be used to simulate complete manufacturing chains of sheet components and the study of how different mechanical properties propagate and influence succeeding component performance.Since sheet metal assemblies are a major constituent of a wide range of products it is vital to develop methodologies that enable detailed evaluation of assembly designs and manufacturing processes.
