The experience gained during the DURAMECH project will be applied in WP7 to optimize the case studies which were selected in WP1. The design guidelines obtained in WP6 will be used to convert welded assemblies in HSS to bolted ones in order to obtain increased fatigue performance, or to transform a bolted assembly of lower strength steel into a bolted assembly of high strength steel that has at least the same static strength, but an increased fatigue performance. The enhanced knowledge obtained during WP1-WP6 will be applied to the industrial case studies to optimize the design of bolted connections in the cross member of a HSS truck chassis, and to replace an S355MC welded cleaning shoe frame for a combined harvester with a HSS bolted assembly.

Objectives

  • Propose guidelines on how to transform a welded assembly into a bolted assembly that has at least the same static strength but an increased fatigue strength.
  • To propose guidelines on how to transform a bolted assembly of lower strength steel into a bolted assembly of high strength steel that has at least the same static strength, but an increased fatigue performance.
  • Demonstration through case studies: optimised design of a cross member in HSS truck chassis, and bolted prototype of a cleaning shoe frame for a combined harvester.
