Abstract
BACKGROUND: Nowadays, cabins of agricultural and construction machinery with integrated roll-over protecting structures are widely used. Using aluminum alloys is one of the ways for significant weight reduction of these load-bearing structures; however, there are issues with mechanical properties of aluminum in the welded joint zone. The recently appeared additive technologies for aluminum alloys help to obtain structures with complex shape that demonstrate high ductility and impact toughness. However, their application in development of roll-over protecting structures requires additional research to determine compliance with passive safety requirements according to the GOST ISO 3471-2015.
AIM: To study the stress-strain state of aluminum alloy specimens and their welded joint for compliance with passive safety requirements according to the GOST ISO 3471-2015.
METHODS: The experiment-simulation approach is used in this study. A universal tensile machine and an impact testing machine are used in the experiment.
RESULTS: The mechanical properties of the samples made of 3D-printed aluminum alloys and their welded joints were obtained. Their degree of compliance with passive safety requirements according to the GOST ISO 3471-2015 was established.
CONCLUSION: According to the conducted study, the potential for use of 3d-printed aluminum alloys and their welded joints in rollover protection structures of cabins in agricultural and construction machinery is confirmed.
