I am hiring a doctoral researcher! Quality assurance is a central aspect of modern mass production in general and core production in particular. Quality assurance for core production and subsequent metal casting is comparatively complex compared to other mass production processes such as metal forming and machining. On an industrial scale, cores are currently inspected only visually before being used in the casting mold. Fine and closed cracks are often overlooked. These defects lead to scrap after casting, which can only be classified as such after a considerable consummation of resources. You will use resonance testing in combination with modal analysis to find such defects in foundry cores. Within the scope of the research project, methods will be developed not only to distinguish between good parts and scrap, but also to localize defects. The video shows the simulated fracture of a water jacket core with a defect during testing.   Do you want to be part of this research journey or do you know someone who is interested? Please write me a private message or comment.   #DDMP #MRM #dieSandler #impulse_exciation #modal_analysis #foundry_cores
