Optimizing design and analysis of airframe, naval ship T-joint manufacturing with vibration assistance and artificial intelligence

Abstract

This research examines the progress of polymer composites in the aircraft and shipping sectors, specifically targeted appli- cations that require load-bearing features, such as the wings of an airplane and fuselages. The Importance of structural performance and safety resulting from are brought to light, as well as the effect of vibration in vibratory wet lay-up to make improvements to existing production techniques. This process of application uses vibrations in the wet lay-up process to enhance interfacial strength between the resin and fibers, in addition to voids and lowering material performance. T-joint designs and the effect of the vibration are investigated to evaluate machinery performance, as well as glass epoxy resin, and foam PVC. The impact of vibration to improve resin flow and minimize defects was analyzed using traditional vibratory wet lay-up methods. Tests used to evaluate mechanical behaviour. For predictive modeling, advanced Machine Learning (ML) techniques, specifically QNNs and the POA were utilized. A hybrid QNN-POA model could deliver the highest predictive accuracy with a mean predictive error of 0.16, outperforming the measured means of all other standard methods. On the basis of the facts brought to light by the preceding work, the bearing capacity potential of the TJ composites was accelerated through the usage of the vibrational-assisted method in making the TJ1 composites, as the tensile testing of 9000 N with a displacement of 8.36 mm, followed by the additional tests of 13,000 N and 11 mm in the bending tests further confirmed the efficacy of the TJ1 composites as the primary material of construction in the high-loaded aerospace application in resistance to the vibrational conditions because of the relative strength and resistance to deformation. Though the TJ2 composites and PVC composites demonstrated good bearing capacity potential, the relative strength was lower than that of the TJ1 composites but with marginally increased deformations.
