ShipWeldFlow
Digital Twins for robotic unit welding analysis and optimization in ship production.
SDU Mech is in involved in Work Package on: Process simulation models for robotic welding of large marine structures for prediction of deformations and residual stresses. The welding simulation model will be developed to optimize the welding sequence of complicated multi-panel structures.
Partners in project: SDU Robotics (Leader), Odense Maritime and Inrotech.
ShipWeldFlow is a Grand Solution funded by Innovation Fund Denmark and coordinated by SDU Robotics. See: https://www.sdu.dk/en/forskning/sdurobotics/researchprojects/shipweldflow
Project period: 2020 to Marts 2025.
Simulation of thermomechanical effects from welding
As part of the ShipWeldFlow project, SDU Mechanical Engineering are working to develop a computational model to accurately simulate the thermomechanical effects from welding on large plates. The temperature fields are calculated using a time-dependent heat source simulating the movement of the welding torch. The temperature fields are then coupled to a mechanical response through a thermomechanical and plastic deformation model. The goal is to predict the macroscopic displacements and deformations of large plates, which will be part of large-scale structures such as ship hulls. Once the model has been validated using experimental data, the long-term goal is to use the simulations to optimise the welding sequence to minimise deflections.
