In this study, the total algorithm of the strength-based design of the system for mass production has been developed. The proposed algorithm, which includes numerical, analytical, and experimental studies, was implemented through a case study on the strength-based structural design and fatigue analysis of a tractor-mounted sunflower stalk cutting machine (SSCM). The proposed algorithm consists of a systematic engineering approach, material selection and testing, design of the mass criteria suitability, structural stress analysis, computer-aided engineering (CAE), prototype production, experimental validation studies, fatigue calculation based on an FE model and experimental studies (CAE-based fatigue analysis), and an optimization process aimed at minimum weight. Approximately 85% of the system was designed using standard commercially available cross-section beams and elements using the proposed algorithm. The prototype was produced, and an HBM data acquisition system was used to collect the strain gage output. The prototype produced was successful in terms of functionality. Two- and three-dimensional mixed models were used in the structural analysis solution. The structural stress analysis and experimental results with a strain gage were 94.48% compatible in this study. It was determined using nCode DesignLife software that fatigue damage did not occur in the system using the finite element analysis (FEA) and experimental data. The SSCM design adopted a multi-objective genetic algorithm (MOGA) methodology for optimization with ANSYS. With the optimization solved from 422 iterations, a maximum stress value of 57.65 MPa was determined, and a 97.72 kg material was saved compared to the prototype. This study provides a useful methodology for experimental and advanced CAE techniques, especially for further study on complex stress, strain, and fatigue analysis of new systematic designs desired to have an optimum weight to strength ratio.

“…The blades of wind turbines capture and convert the wind energy into rotational energy to induce the turbine generator to produce electrical power. Thus, wind turbine blades must meet several criteria for efficiency, including lightweight, resistance to extreme fatigue loads, constrained tip deflections, avoidance of resonances, and cost-effectiveness [8][9]. Producing efficient blades with such criteria is challenging and may come at the expense of giving up some structural specifications.…”

“…3D printing provides many benefits, including better design possibilities, remarkable ease of producing intricate and detailed geometries, and reduced need for surface-finishing [11][12]. 3D printing involves placing and consolidating materials layer-by-layer, depositionsing a Computer-Aided Design (CAD) file sliced into thin cross-sectional layers [6][7][8][9], illustrated in Figure 1. Layers are sequentially printed and solidified using specialized machines or 3D printers that employ different techniques, such as powder bed fusion, material extrusion, or directed energy deposition [10][11][12].…”

3D printing optimizes wind turbine blades for greater cost-effectiveness and durability.• The review emphasizes design optimization to enhance aerodynamics and structural efficiency. • Challenges such as material limitations and the need for structural integrity are identified. • AI and hybrid manufacturing are proposed to address these limitations and reduce costs.Wind energy has become an easy-to-harness source by converting captured wind currents into electrical energy. Powerful and customizable wind turbines are used to convert wind energy efficiently. However, wind turbine development in terms of structure is still an active area of research aiming at efficiently building capable and long-lasting turbines. Additive manufacturing technology, particularly 3D printing, has revolutionized multiple industries, including its potential to create wind turbine blades with high cost-effectiveness and optimizable shapes and rigid structures. In this review, various 3D printing-based techniques, including Fused Deposition Modelling (FDM), Continuous Fiber Reinforcement (CFR), Stereolithography (SLA), and 3D Printing-enhanced Large-Scale Additive Manufacturing (LSAM), are examined in detail for complex and large-scale wind turbine blade production. Materials used in 3D printing wind turbine blades, such as thermoplastic composites, epoxy resins, and fiber-reinforced polymers, are assessed with a focus on their mechanical strength, durability, and environmental considerations. Furthermore, the importance of design optimization and customization for wind turbine blades, including aerodynamic and structural design optimization, is emphasized. Customization for site-specific conditions, infill structural optimization, and infill printing speed and cost are also discussed.The review highlights the importance of structural optimization in developing efficient and cost-effective 3D-printed wind turbine blades, customization for sitespecific conditions, and infill structure. The review also mentions these technologies' challenges, such as material limitations, surface finish quality, size limitations, and structural integrity. Therefore, addressing these challenges to utilize these technologies' potential fully is crucial.

Small wind turbines (SWTs) face tremendous challenges in being developed into a more reliable and widespread energy solution, with a number of efficiency, reliability, and cost issues that are yet to be resolved. As part of the development stages of an SWT, testing the resulting efficiency and determining appropriate working ranges are of high importance. In this paper, a methodology is presented for testing SWTs to obtain characteristic performance curves such as Cp (power coefficient) vs. TSR (tip–speed ratio), and torque vs. ω, in a simpler and faster yet accurate manner as an alternative energy solution when a wind tunnel is not available. The performance curves are obtained with the SWT mounted on a platform moving along a runway, requiring only a few minutes of data acquisition. Furthermore, it is only required to measure a single variable, i.e., the generator output voltage. A suitable physics-based mathematical model for the system allows for deriving the desired performance curves from this set of minimal data. The methodology was demonstrated by testing a prototype SWT developed by the authors. The tested prototype had a permanent magnet synchronous generator, but the methodology can be applied to any type of generator with a suitable mathematical model. Given its level of simplicity, accuracy, low cost, and ease of implementation, the proposed testing method has advantages that are helpful in the development process of SWTs, especially if access to a proper wind tunnel is prevented for any reason. To validate the methodology, Cp vs. TSR curves were obtained for an SWT prototype tested under different test conditions, arriving always at the same curve as would be expected. In this case, the test prototype reached a maximum power coefficient (Cp) of 0.35 for wind velocities from 20 to 50 km/h for a TSR of 5.5.
